Sony NW-A45 Walkman

The NW-A45's compact size makes it easy to take anywhere (headphones not included).

Support for high-resolution audio files

The NW-A45 is compatible with high-res PCM-based files (up to 24-bit/192kHz), DSD (Direct Stream Digital) files, Apple Lossless, and other formats. For low-resolution files, such as MP3s, The player is also MQA-compatible.

Sony's Digital Sound Enhancement Engine can help them sound fuller. The built-in rechargeable battery can deliver up to 45 hours of operation, so you can enjoy music all day and then some.

High-res Bluetooth streaming

This player also has built-in Bluetooth for wireless music streaming. On top of that, it features Sony's LDAC technology, which allows the wireless signal to retain more musical detail with compatible Sony speakers and headphones. We recommend pairing this player with Sony's best Bluetooth headphones — the WH-1000XM3 wireless noise-cancelers — for a super-sounding portable listening rig. 

Storage for high-res files

The 'A45 features 16GB of built-in storage. If you need more memory, the player's microSD card slot can accommodate up to a 128GB card.

Now This is What Portable Entertainment is All About

Crutchfield customer from Somerset, NJ on 6/3/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Needed a replacement for my 16GB ipod, which could not hold anymore music. Only wanted a pure music playing device with expandable capacity. Was to referred to the Sony NW-A45 on the recommendation of Rep. Kay, and she and The Walkman did not dissappoint I thought plugging my Shure SE425 earphones into my iPod was good. Plugged them into the NW-A45 and the music jumped out by leaps and bounds. The sound, the range, the depth of the music. From Moby to The Beatles to Gorillaz to Beach House I am hearing detail I have never heard before. One or two calls to Tech Tim, and I and the NW-A45 were good to go. So glad I contacted Crutchfield...................Again!

Pros: Super easy to download songs/albums. And again, unbelievable that a hand held device gives such great sound.

Cons: Does not always show album/song artwork. Have to use the power button to open the screen/would have preferred it opening by pressing the screen.

The audio signal is great, the size is compact and easy to handle. File management I've found to be counterintuitive and the on line help manual is poor.

Pros: Size and audio playback

Cons: Delicate controls are glitchy (brush the player and it may stop. File management is counterintuitive. On line manual..not so helpful.

Great for lossless Files

Crutchfield customer from Clyde, NY on 5/22/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

First observation is that it will not play WMA Lossless files. My entire collection is made up of these files. I was initially going to return it, then I played some WMA files. Then I ripped some FLAC files. Using a set of Bose Soundlink II with the wired connection and EQ setting on Sony preset EDM. Definitely worth the sale price minus my 55 dollar reward dollars. The FLAC files are fuller and very clean, the EDM setting gives great bass at lower volumes with no need to turn the volume way up. Has a selection feature for specific Sony headphones, which might be good for some. I paid 120 plus reward points which makes this best in that price range. I am keeping it and slowly ripping Flac files to enjoy. If your serious about your music and have lossless files that it will play its a must have. If your using simple mp3 files or a downloading service I would say no.

Pros: drop and drag from Windows Media Center is Awesome

Cons: Will not play WMA Lossless files, but to get a player that will cost you twice as much

Good Little Device

Dana from Kasson, MN on 4/4/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

This unit has very small screen, but is just right for storing hi-res music files. The internal storage is also small, but it takes a 128GB micro SD . The Bluetooth connectivity is good with all but one of my devices, and the file transfer is very easy and efficient. I was skeptical at first, but I download almost all hi-res files and it is a pain trying to still use iTunes. This unit, I feel, is a very good purchase for the price. Supports most file formats, and delivers some pretty high quality sound to my systems and headphones wired with 3.5 aux or Bluetooth. I haven't had it long enough to evaluate battery life, but so far so good. USB is for file transfer and charging. I carry this in my work car and truck mostly, but also good on the main systems in the house. I have some Bluetooth connectivity issues with my vehicle (Honda Pilot) and TV sound box (Pioneer).

Pros: File support

Cons: Doesn't play through USB

Sony nw-a45 Great Product

Joe from Clinton, MS on 2/25/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Crutchfield,"Thank You" for your absolutely great customer you are the best! My recent purchase of the Sony nw-a45 Walkman is my 3rd Sony mp3 player. My first sony is a nwz-545 and still plays fine even after nine years. From tv's to dvd players Sony makes a good product period! It seems to me most all music players and electronic componants have a few quirks or small issues with them no matter what brand they are. I don't like the way this new sony nw-a45 files a few of my albums but I'm ok with that. I love this mp3 player and I'm thinking about buying another one. Try buying a nice stereo for your house or car and see much it will cost you. For the 219.00 I spent on this sony,it was money well spent,even a bargin considering what I'm getting in return!!!!

Pros: Sound quality,convenience,easy to use,functions and features are great!

Cons: Have to look for a few of my albums

Verified employee purchase (What's this?)

This is a great player. I can now get away from Apple and ITunes after a long and dreadful experience with music. I have tons of stuff that now plays in beautiful high quality sound. I also love the ability to blue tooth to my 5.1 speakers. This is a major update to my original Ipod which I have had plugged in for years since the battery died. Once unplugged, it died forever. Very happy with the size and functionality of this Walkman. Soon I plan to even upgrade my flip phone.

Would purchase again

Paul from Fairview, NC on 10/30/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I really like this HD player! Sound quality is excellent both over Bluetooth in car and using quality headphones (Sein Hxxx) User friendly and easy for me to navigate the device. I'm giving it only 4 stars because it seems to periodically have issues connecting to my Kenwood car bluetooth deck. But not sure which is to blame. It may be the Kenwood.... or it may be the Walkman. Takes a forced connected using the Kenwood setup at times to reconnect. My phone connects with the Kenwood for hands free calling, and doesnt seem to have issues. But... I'd purchase the Sony again without hesitation.

Pros: Quality sound, easy to navigate, long battery life

Cons: Connection to BT

Great product with great sound. Easy to connect to external speakers using Bluetooth. Using Sony Music Production Center to upload songs and album art (very important).

Pros: Easy to use device, and Sony Music Production Center was critical for me to upload music and album art

Cons: Small screen fonts for an older user - album art becomes critical to recognize albums to play

Sony NW-A45 Walkman

Crutchfield customer from Ridgefield, NJ on 10/28/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Quite an improvement over an earlier Sony model i purchased 4 years ago. It's sound, ease of use and built in radio make it my go to for commuting and travel. The expandable micro SD slot gives you enough memory for pretty much all the music/audio books you'd want to put on it.

Pros: Easy to carry and gives you a great sound through a variety of headphones. Built in DAC for use with laptop listening. Great value!

Cons: A little thicker than some of the other models in the previous Sony line. A protective case will be a good investment as the player can easily slip from your hand.

Great digital music player!

Brian from Auburn, ME on 10/10/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

The unit feels well made and looks really nice. Music sounds great. Bluetooth connectivity works flawlessly. Having the EQ work when using Bluetooth would be nice, but still sounds pretty good without it. The only thing I find annoying is that it creates a database of what is on the microsd card whenever you turn it on. I can see when you insert a card, but every time you turn it on is a bit ridiculous. Other than that, it is a great product and I highly recommend it!

Pros: Sound Quality Looks

Cons: A bit pricey Database creation every time you turn it on

A lot of great music from a small device.

w.a. from Jesup, GA on 10/8/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I usually listen to music in my truck from a walkman with a list of music that I have compiled over the years. I'm a baby boomer and prefer my music from my time along with new hits that catch my ear. My previous walkman (NWZ-F806) died. So with Crutchfield's help,I purchased this replacement. Works just fine with my Sony car radio, and sounds great.Already populating it from the 900 songs I have on my playstation 3 which I use as a media player in my home. The extra memory card slot ensures plenty of jams for long trips,and with shuffle mode from the radio and a remote control, I never hear the same song twice. Thanks Crutchfield! I'm back in the groove.

Overall a Good Product

Tim from Anchorage, AK on 10/7/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

The sound quality is good; its certainly very compact yet has reasonably sized controls for the critical functions. The screen display is crisp and easy to read even for someone that needs reading glasses for smaller fonts. The Sony software for managing your music collection is fairly easy to use and intuitive. Setting up playlists was straight forward. Transferring music was much faster than expected. Bluetooth pairing was easy but unfortunately its buried in the Settings menu. A Bluetooth On/Off icon would be a nice addition. No carrying case, it requires a proprietary cable and has a fairly small memory, which are disappointing for a unit at this price point.

Pros: Compact size, easy of use for both the Walkman and the Sony Music Center software.

Cons: Proprietary cable required, no case is included, memory size is fairly small for this price point,

Crutchfield is great, Sony Walkman... ehh?

Russell from Clayton, NC on 8/28/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

My order experience was fine with Crutchfield, as always. I am not, however, loving the Sony Walkman i bought. Mainly because of a lack of documentation/ Manual, on Sony's part. The menu on the player itself, is only half intuitive and that , when trying to integrate it into a system, or use with basic BT speakers, for example, rather than just using it as a portable listening device... is only a half- satisfying experience. The lack of volume control from the Walkman when connected via BT... even in it's "Enhanced Mode"...causes one to use only a BT speaker with it's own vol. adjustment (a far more costly type) as the signal is way to 'hot' otherwise. The rest of the product and it's software which is needed to make playlists, etc. is, for me, too much WORK... so, i made a poor choice. All's well with Crutchfield, as mentioned, though.

Pros: nothing stands out

Cons: no vol. control when connected via BT and software used on computer to organize is too much work.

Poor sound quality.

Crutchfield customer from Nathrop, CO on 8/22/2018

Verified employee purchase (What's this?)

This product has decent sound if you keep your headphones plugged in, once you switch to Bluetooth all of the sound controls (except volume) don't work. For someone who wants to listen to mid range only this might be O.K., but if you want bass and treble in you music, while listening with Bluetooth headphones this is not for you. I have wasted my money.

Easy to load but lacks extras compared to others

Alan from Oakland, CA on 8/20/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Lack of internal headphone amp means you have to buy one for your nicer Cans. Also doesn't have a Line Out capability; you have to use a regular headphone cord and turn up the volume when running a headphone amp. So far easy to use and load with music but is idiotically picky about some tracks (won't hint as why it doesn't like them).

Pros: Loads easy, good on data cards, simple controls, polished feel

Cons: No line out, no internal headphone amp, no data cord for headphone amps

Nice little unit!

Dave from Dekalb, IL on 8/7/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I am enjoying this little player very much. I have it connected via Bluetooth to my 2018 Subaru. The connection was simple and fast. In the process of importing files from my computer about 40% of the album cover art did not make it? I guess that's not much different from iTunes? It was relatively easy to get it added, just time-consuming. The Sony Music Center software is pretty simple & the transfer to the Walkman is a "drag and drop".

Pros: Compact size, decent sound, good Bluetooth connection.

Cons: Not as easy to set up playlist "one the go" (compared to iPods)

Easy to use! Slightly larger than a business card. Color screen for album artwork. 3.5mm jack for headphones. FM radio. Great Sony App/ software, is compatible with windows 10!

Pros: Battery life great. Expandable memory. Clear, crisp sound with equalizer. Great sound & hook up to my car via 3.5mm jack.

Cons: This is a tad bit slow on the start up; however, it is a great product. I haven't tried the bluetooth yet.

Cost effective solution for playing uncompressed FLACs.

Stu from Evanston, IL on 8/5/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Picked this puppy up to play FLACs in my new car which does not have a CD player. Hooked into my car's AUX input, getting much better sound quality than from MP3s stored on my phone. Easy to work with. Very intuitive. Simply dragged and dropped files from music collection stored on my computer to the Sony. Unit comes with 16 GB of memory, but can add up to 128 GB more via micro SD card, which I did. Currently have around 150 albums on the player, all stored as uncompressed FLACs and guessing room for a 100 more. (With compression, you could store way more music, with some trade off in sound quality, but personally I'm dead set against compression ... that is why I bought this player.) Very cost effective solution for my use case. Delighted with the product.

Pros: Great SQ and functionality for the price, and all in a very small package.

Cons: Wish I could make icons a little bigger .... but not a deal breaker.

Excellent, straightforward player for HiRez

David from New York, NY on 7/29/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

So far, this is exactly what I was looking for. A compact replacement for my ipod classic that would also play FLAC files as I build out my HiRez collection. It is intuitive to use and offers a significant improvement in sound quality over an iphone or ipod, even with standard resolution material. Two minor points that could add a star: (i) ditching the proprietary cable for USB-c or another universal protocol; and (ii) some sort of a belt clip or aftermarket case to make it more gym friendly.

Pros: Great sound quality, intuitive operation.

Cons: Proprietary cable. Lack of belt clip or case for gym use.

Love this MP3 player. My only negative comments would be the instruction manual that comes in the box is a real O. And I cannot connect the Bluetooth to either of my Honda vehicles.

Pros: Easy to use. Great sound quality. Well made product.

Back to basics portable music

Matt from Fort Collins, CO on 7/16/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Does one job and does it well ... plays music with no distractions ... no wireless, no phone, no text messages, no browser. It doesn't even tell the time. This is a good thing. It brings me right back to the last Walkman I owned which was Minidisc based. Great for finishing my workouts without the interruption that happens with an iPhone. It also sounds 100x better, works faster, and doesn't pester me to sign up for "Apple Music", suggest things I should be listening to instead, or tell me to follow my favorite artist on social media. Also, the Sony music manager application for Windows isn't half bad, it's no frills but it runs circles around the iTunes bloatware that you have to use if you want to manage your music in Apple's world. This gadget also doubles as a DAC for your laptop, and the Sony PC software can function as a pretty capable player or you can download the hardware driver from Sony and use the windows player of your choice. You will probably want a memory card, I haven't gotten one yet but I'm hoping it supports 256GB capacity when I do. Also I wish it had included a carry case ... Sony always used to include a case with walkmans. The selection online is pretty limited. If you want to go back to basics for portable music this is your answer. Your friends may laugh because you are carrying a Walkman again, but it's such a relief to disconnect from a smart phone for a while and just have a really good sounding port

Pros: Sounds great. Great battery life. Easy to use, fast interface, capable PC software, no unneeded features, no distractions. Just simple music on the go.

Cons: Limited selection of accessories available online (cases, cables, etc.). Proprietary cable ... not standard micro USB... you'll want to buy a spare. Sony could have included a protective case. Finally you will also probably want a memory card.

Works and sounds great. Needs a bit of work in the UI department but aside from that, a great buy.

Pros: Good size. Easy to use. Quality build. Great sound

Cons: UI is a tad sluggish. UI is not up to par with modern Mobil devices (IPods) Data transfer software needs improvement.

Guitars have strings again, cymbals vibrate, violins are cool....The clarity of the sound makes the recording come to lfe. I had an early IPod Classic, now an iPod touch with 10,000 songs and this new Sony Walkman NW-A45I can cut grass with my diesel Zero Turn Mower or my bushhog on the back of my Kubota L-38-30 tractor and still enjoy quality music reproduced, Bose Sport Ear Buds. Not bad for the suburb of the Sticks in Sharon, Ga.

Pros: Music reproduction. battery Life

Cons: Ease of finding songs. I ran in to several sites that stated the Sony would not be compatible with I tunes collections but My file seems to have been imported by the Sony Walkman with the exception of playlists that were not imported. JW was the Crutchfield associate that helped me.Like Brooke and a couple of others have been very knowledgeable. I will be playing my music next year at our 50th High School Class Reunion. I'm fairly certain that one of t is steered me towards a Denon Am

Product Research

Features

Overview: The Sony NW-A45 is a Hi-Res Walkman digital music player, capable of playing high-resolution audio files. Hi-Res audio (24-bit, 96kHz and up) transmits 3.2x more data than CD audio (16-bit, 44.1kHz), allowing you to hear more detail and nuances in your music. The NW-A45 also has Bluetooth Audio Streaming with NFC technology for easy connection and wireless listening. The unit features a 3.1" LCD screen, and an internal 16 GB flash memory. You can add even more memory by inserting a microSD card.

Supported Audio Formats: The NW-A45 Hi-Res Walkman can support multiple digital audio formats:

MP3 32-320 kbps (incl. VBR) at 32, 44.1, and 48 kHz
WMA 32-192 kbps (incl. VBR) at 44.1 kHz
FLAC 16, 24-bit at 8 and 192 kHz
WAV 16, 24, 32-bit at 8 and 192 kHz
AAC 6-320 kbps at 8 and 48 kHz
HE-AAC 32-144 kbps at 8 and 48 kHz
Apple Lossless 16, 24-bit at 8 and 192 kHz
AIFF 16, 24, 32-bit at 8 and 192 kHz
DSD 1 bit at 2.8224, 5.6448, and 11.2896 MHz
APE 8, 16, 24-bit at 8 and 192 kHz (Fast, Normal, High)
MQA Supported

Design: The NW-A45 features solid build quality with a 3.1" TFT WVGA color display (800 x 480 pixels) with white LED backlighting. It has a capacitive touch screen for on-screen control. The circuits and components are attached to the circuit board with a Sony-developed high-quality, lead-free solder for a purer signal path. The S-Master HX digital amplifier is optimized for high-resolution audio playback, delivering smooth, natural sound over a wide 20Hz-40kHz frequency range.

DSEE HX: Sony has included their DSEE HX "up-scaling" technology in the NW-A45. DSEE HX uses an algorithm to analyze the music, and automatically replace the "lost" information. DSEE HX (Digital Sound Enhancement Engine) gives your highly-compressed music files new life so they sound almost as good as true Hi-Res Audio quality.

Memory: The NW-A45 has a 16 GB internal memory, which has the capacity for the following number of recordable songs (approximately 4 minutes in length):

  • MP3 (128 kbps): 3,300 songs
  • AAC (256 kbps): 1,600 songs
  • FLAC:
    • 44.1 kHz/16-bit: 300 songs
    • 96 kHz/24-bit: 90 songs
    • 192 kHz/24-bit: 40 songs
  • DSD (2.8224 MHz/1-bit): 70 songs
Note: Actual user memory is approximately 12.26 GB, as a portion of the memory is used for data management. The unit's memory card slot will also accept microSD cards for even more memory capacity.

FM Tuner: The NW-A45 has a built-in FM tuner for listening to radio broadcasts. The frequency range of the FM tuner is 87.5 to 108.0 MHz. The FM tuner can be turned on when a pair of headphones are connected, as the headphone cable serves as an antenna. Up to 30 FM stations can be set as presets, manually or automatically.

Bluetooth/NFC: With built-in Bluetooth 4.2, you can stream your music files wirelessly from compatible devices up to 30 feet away. Devices that have the NFC (Near-Field Communication) function, can be automatically turned on, and paired with the Walkman, by simply touching the back of the Walkman to the device on the NFC logo. The NW-A45 is equipped with LDAC, which uses the conventional Bluetooth connection, but transfers data at up to 999 kbps. That's three times the transfer rate of other audio profiles, which results in higher fidelity. In addition, the unit supports aptX and aptX HD.

Sound Quality Settings: You can adjust the sound quality with the following selectable functions: 6-band Equalizer (with presets Rock, Pop, Jazz, Classical, EDM, R&B, HipHop, Relax, and Custom 1&2), DSEE HX, DC Phase Linearizer, VPT (Studio, Club, Concert Hall, Matrix), Dynamic Normalizer, ClearAudio+, and Clear Phase.

Special Modes with Sony Headphones: The NW-A45, when used with certain Sony headphones offer extra listening modes. These functions should be turned off if using incompatible headphones to save battery power:

  • Noise Canceling: Headphones with Noise Canceling include the IER-NW500N, IER-NW500NE, MDR-NW750N, and MDR-NW750NE. The Noise Canceling function reduces ambient noise, and allows you to listen to your music at a low volume.
  • Ambient Sound Mode: The IER-NW500N and IER-NW500NE also have an Ambient Sound Mode, that allows you to hear ambient sound, even while wearing headphones. It uses the built-in microphones to pick up and amplify ambient sounds to help you stay aware or your surroundings.

Rechargeable Battery: The Walkman has a built-in Lithium-Ion rechargeable battery for exceptional stamina. After a 4-hour full recharging time (via USB connection), the unit's estimated battery life is as follows:

  Ambient Sound Mode Off / On Noise Cancel Off / On
MP3 128 kbps 45 hrs / 30 hrs 45 hrs / 37 hrs
AAC 256 kbps 39 hrs / 27 hrs 39 hrs / 33 hrs
FLAC 96kHz/24-bit 39 hrs / 27 hrs 39 hrs / 32 hrs
FLAC 192kHz/24-bit 30 hrs / 23 hrs 30 hrs / 27 hrs
DSD 2.8224 MHz/1-bit 25 hrs / 20 hrs 25 hrs / 22 hrs
Radio --- 32 hrs / 27 hrs
Direct REC 8 hours MP3 (128kbps)
Bluetooth MP3: 20 hours (SBC connection)
FLAC: 13 hours (LDAC, Auto)

Connections/System Requirements: On the bottom of the unit is a 3.5mm stereo headphone output, plus a 22-pin WM-PORT for connecting the unit to a computer using the supplied USB cable. The NW-A45 is compatible with computers with the following operating systems: Windows 7, Windows 8.1, Windows 10, and macOS v10.8-10.12. You can also use the WM-PORT to connect the unit to one of Sony's Headphone DAC/Amplifiers, such as the PHA-1A or PHA-3 (special cable supplied with the headphone amplifier).

  • Frequency Response: 20 Hz to 40 kHz
  • Audio Power Output: 35mW + 35mW max
  • Dimensions: Width 2.2", Height 3.839", Depth 0.432"

My battery on my Hi Res Sony Walkman NWZ-F806 died. I was using this via usb to my Sony car radio. Sony just responded to my query as to whether this Hi Res Walkman would also work via usb with stated radio.( radio model # CDX-GT575UP). Crutchfield said it should, and Sony said it would. So when I saw the 61.00 in Crutchfield rewards that I had acquired that could be used with this purchase, and free shipping, well it was a no brainer. [ T  Oct 03, 2018 ]
A
I chose this MP3 player because I prefer to listen to music on a dedicated player, and because my current Walkman has excellent sound quality. [ Elizabeth  Sep 21, 2018 ]

I still have and use my old Walkman. If this new Walkman with all it's extras performs as well as the old one, it is sure to increase my enjoyment of my music collection. Also, I won't expect to have to buy another one for a really long time. [ Paula  Jul 25, 2018 ]

I chose the Sony Walkman to playback my music library on the go in my car, in my boat, or in my home. My old IPOD classic battery will not charge Apple does not support that product with battery replacement. Good bye to Apple Hello to Walkman. Again. My last Walkman played cassette tapes! it was great. Then. Colt answered my questions prior to placement of this order. Thanks Crutchfield for your superior service. [ David  Jul 24, 2018 ]
A
Just kind of curious to see how far the walkman has come from the old cassette tape days. Being on sale doesn't hurt either. Sony was once the only choice for portable audio, so I am really curious to see how this product performs. Not that I am a audiophile or anything like that. Just a guy that likes to listen to music.

Bluetooth capable, expandable memory. I've always bought reliable Sony products. [ Z  Apr 16, 2018 ]
A
Very much love the idea of having my whole library organized on a music only device which will release memory space on my iPhone X. Also, beginning to develop quite a collection of high def FLAC files that will nicely transfer via Bluetooth to my McIntosh MHA50 then on to my Mc Integrated Tube amp via AQ Sydney.....should be a great addition to some pretty pristine music, as close to vinyl as possible? Thanks Crutchfield! [ Michael  Jun 10, 2019 ]

Need update for my HD, Sony is the best and great service from CRUTCHFIELD [ Joan  Mar 29, 2019 ]

Q
Is there any round-a-bout way to transfer over Master or Hi-Fi quality tracks from Tidal to the player?
[ K  Nov 08, 2018 ]
1 answer
A
Hi; I understand that Tidal sells a subscription for use of their music library. My experience with this service is excellent, but the only music you can actually transfer is the library you paid for.

Hi Lisa I bought a couple of SaDisk micro cards 64G on sale at COSTCO. Put one in and increased my storage capacity substantially. If I need more I'll probably buy a higher capacity card. I hope this helped. Good Luck Vince H
[ vince  Aug 14, 2018 ]
A
You can add a 128GB card as max. Some people are claiming you can use a 256GB card but I believe they are mistaken. Your best bet is to contact Sony directly. I am using a 128GB card and the unit reads it with no problem.
[ MONTE A  Aug 14, 2018 ]
Q
I have a Sony NW-E394 that I use at the gym. The FM reception is very poor. Headphone cord serves as antenna. Would this model be any better or is this a weakness common to all of these little portable players?
[ Karl  Jul 25, 2018 ]
1 answer
A
I'm afraid we don't have enough information on the Sony NW-E394 model to compare the tuner quality to the NW-A45 model. However, the NW-A45 has a built-in FM tuner with a frequency range of 87.5 to 108.0 MHz. And similar to what you described, the FM tuner can be turned on when a pair of headphones are connected, as the headphone cable serves as an antenna. For more details or to discuss further, please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks!

If you load them onto the memory in a compatible file format, absolutely.

Q
Can I download my I tunes library onto the NW-A45 ?
[ Jimmy G  May 19, 2018 ]
1 answer
A
Yes. You have to transfer it through Sony's software, but yes. I have not however tried, older, protected files. I've only used ALAC files, as I don't want the lower quality files in the device.
[ Omar  May 20, 2018 ]
Q
I am assuming you can plug it in via usb to a headunit in my vehicle?
[ Ledzepp 1977  May 19, 2018 ]
1 answer
A
Sorry, no. USB is a digital connection so, you wouldn't want to connect the player this way as it would bypass the Sony's high quality digital to analog converter. If you want to connect the Sony to a car stereo, the better option would be to use the analog headphone output connected to an auxiliary audio input on the stereo. For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: https://www.crutchfield.com/support/ContactUs.aspx
[ Ryan  May 31, 2018 ]  Staff
Q
Can you upload music and album artwork like I do now on my I pod from I tunes?
[ Ledzepp 1977  May 19, 2018 ]
1 answer
A
You can upload both. Just not exactly the same way. Not all artwork seems to be compatible. I had to update some artwork in iTunes for it to be compatible with the Walkman. You will use Sony's software to transfer data from iTunes to Walkman (drag n drop). Easy, but tedious.

Yes, it has plenty of volume levels to work fine with whatever headphones you use.
[ William  Nov 05, 2018 ]
