Wowza

These headphones have some of the best sound quality I've heard from over ear headphones. They are super comfortable and stayed put on my head pretty well! The thing I would comment on is that they are pretty darn heavy which can put a little strain on your neck, but honestly for the sound quality its totally worth it!

Impressive Bluetooth

I'm normally pretty skeptical of how good Bluetooth headphones can ACTUALLY be, as I'm dedicated to a hardwire connection. These blew my expectations away. Great staging and detail!

Great Headphones, Sound and Comfort

Amazing sound when hard-wire connected to the DAC. Excellent sound, though noticeably less clarity, when connected via Blue Tooth directly to the Mac. Intermediate clarity when DAC connected to the Mac and headphones connected to the DAC via Blue Tooth. Modern Blue Tooth is simply amazing. I can walk around the entire apartment, upstairs and down, using Blue Tooth. For best sound I use hard wired connections, but for maximum convenience I use Blue Tooth. Noise cancelling is surprisingly good, especially for droning noise like kitchen exhaust fans, but the headset does a great job even with shrill sounds like kitchen timer alarms.

Best Bluetooth Headphones yet

Upgraded from JBLs and the first thing you notice is the weight and the quality of the material. These are definitely audiophile headphone. It's not overbearing and I spent about 6 hours with them on my first outing. Sound quality is crisp and the app allows for adjustments to fine tune it. The noise cancelling is so good it's almost scary. I had someone sitting next to me tap me on the shoulder because I couldn't hear a word they said.

Not that impressed as expected

A little bit disappointed due to the fact that you can not use mic for headset mode while the headphones are in passive mode, i.e. this unit can be used as a headset only in the blue tooth mode, otherwise this is a set of headphones, not a headset. It is nit good for gaming, the sound quality of BT connection with my high end PC is practically unacceptable (because of the PC), I have verified that 5909 sounded good being connected to my iPhone. Not sure if any PC motherboard with good BT audio even exists. Overall, the sound quality of 5909 even in passive mode is not that impressive as I expected, on par with my Audiotechnica ATH-M50x headphones. Such as I have 2 relatively good portable headsets, most probably will return the item, nothing in it worth $1k+ in my humble opinion.

Not worth Open Box savings. But from Manufacturer!

I really wanted to love these. I know I saved a couple of hundred buying "used" or "Open Box," but still to have them be complete failures, and then, Crutchfield charging me to return them? Not cool, Crutchfield, not cool. Besides spending over this much for a set of headphones, to be nick-picked and charged $12 to return defective headphones is just not right. At first, they sounded good, but no control over anything. Having to press the on-off button took too many times to turn it on, it should have been a flag right then. After downloading app, I got some adjustments. Then it started cutting off, or rather pausing, all music/sound to the headphones (HP). I deleted app, repaired the HP to the iPhone, but still, paused for no reason, sometimes loosing connection. No wonder they were open box. Someone else returned the defective HP! I know it?s only $12, on top of the purchase price, but they failed, and I get charged? I don?t think I?ll be using Crutchfield again. Also, they would not stay on my head. Yes, I may not have any, or much, hair left, but still. Any subtle movement sent the headphones moving back and forth off my gorgeous dome. The Bowers & Wilkens new ones, my Bose 45s, they don?t move around on my one brain cell protective cover, at all. These, they MOVE TO THEIR OWN BEAT! The packaging is what I expect on a "premium" product. One lost customer....

Good, but...

I have mixed feelings. I like the sound, depending on the song. I have a wide taste in music and these showed their quality and flaws. They are pretty well balanced in the low, and mids, but the top end, in the like 10kHz area, is brutal. I was listening to some pop, Rihanna / Beyonce, then Goldfinger / Diamonds are Forever by Chaka and Eric Clapton unplugged. The sibilance is tiring and you quickly realize that you are tired of listening to these no matter how comfortable they are. If you are not sensitive to the top end then these will be good for you. I prefer the balanced more warm sounds of the Focal Bathys - if only the ANC didn't suck on those (I take a bus to work and the bumps of the ANC trying to cope were brutal) - Focal give me an OFF MODE, please - I will buy these again. I promise. The headphones sound great for podcasts which I listen to often as the additional brightness often allowed me to lower the listening volume. One, well 2 last things. There is an incessant hissing when the headphones are about to do something. Its not insanely loud but you can hear it. It doesn't go away for quiet songs or podcasts. Lastly, the ANC, on this pair when engaged, sounds like you have transparent mode on and you're dragging the mic against your clothes. This only happens when you turn left or right for me. When connected to 2 devices songs would randomly stop playing, no idea why. I would have to pick up my ipad / phone and put it back to sleep for it to stop doing t

If you're looking for more from bluetooth headphones...

If you're questioning whether to spend on these.... don't, just purchase. Spent quite a while debating, checking out reviews and so on trying to determine whether or not to purchase. While 'brick & mortar' stores are becoming fewer and fewer - its become more difficult to simply go and listen to something without traveling a distance to find something where 1st hand demonstration can be had. The more you listen to them, the more you are drawn in. As you begin to put some hours on them - the sound flourishes. As expected, the better the source - the better the sound. These have become my defacto favorite for on-the-go listening. As some have mentioned, the price without the ability to listen prior to purchase is a bit off putting. Only long term concern is noted in the "cons". While these are at the top for bluetooth headphones by price - the resultant sound (IMHO) justifies the price. Using a quality headphone amplifier (my preference is tube-based) with lossless source really showcases the capabilities of these headphones. Kudos to Mark Levinson for a well executed design. Sound over bluetooth from Apple devices is still quite nice, albeit despite Apple's limitations. Did try using a Dragonfly Cobalt (Lightening to USB) and they did sound notably better, but adds bulk/cabling/etc. Using a dedicated DAP is certainly worthwhile.

Amazing, though pricey, headphones

Very impressive headset. Easy to use and truly amazing sound out of the box. Perhaps too good as the headphones, like other high-end equipment, reveal the limitations of the source material. Positives: Snug fit, easy to adjust, simple controls, nice to have an app to adjust bass and other items. Tried them out with a variety of different kinds of music and all sounded excellent. Opportunities for improvements to the next models: The iPhone did not recognize the headset using a direct connection (USB-C to lightning). It would only recognize it when using the adapter (3.5mm jack to lightning, USB-C to 3.5mm). Maybe a minor inconvenience, but disappointing because lossless only works with a wired connection, not bluetooth, and needing yet another adapter is a bit annoying, especially since the kit came with a variety of cables to use. For the price I paid I don't want to add an external DAC/amp. Note that on the MacBook Pro wired connection the sound was amazing.

ML 5909's set themselves apart from the pack.

These headphones are very unique experience within the ANC Bluetooth headphone space. I'm of the mindset that beryllium can be heard when it is used as a component within drivers, be it speakers or in this case the headphone drivers, and that sound is one that is particularly detailed that elevates/pulls out vocal detail and has a crispness and clarity that you will not find anywhere else. I feel that this will be most enjoyable for people who enjoy classical, acoustic, or orchestral music (as opposed to rock or electronic). Furthermore the 5909's the bass control is impressive. You definitely will find more bass presence and impact in the PX8's for example, but the overall speed, control and detail of low frequency sound of the 5909 is without comparison. It's just a tighter more managed bass, not overflowing or rotund. The sound field depth of the 5909 is somewhat controversial in that it's hyper detailed sound makes so much of the music forward and present that the depth front to back may seem slightly lacking compared to other headphones which muddy low frequencies making sounds more distant while having mid and high frequency sounds up front. Overall the 5909's have a sound signature that is very enjoyable and detailed, one that no other ANC headphone replicates. I can definitely say given their price point they do separate themselves from the competition and provide a quality product that has numerous distinctions that you will only find in owning the 59

Mark Levinson No. 5909

I was looking for a wireless headphone with a good feature set (e.g. ANC, comfort) but with better sound quality than the leading contenders (e.g Sony and Apple). On research these seem to fit my requirements the best. I also like the fact they can be connected without power, combine that with an external dac and sound is awesome. Sound is also very good in wireless mode (significantly better than the mid tier offerings). AnC is just average at best (no where as good as Sony XM5). Comfort is great. The APP is disappointing in that it has no equalizer other than a bass enhancer. For the price this should be addressed. I do not like the fact that ANC goes into awareness mode only (can't be changed) during phone calls. I had some quality issues with this purchase (not from Crutchfield as the support is great) though with defective units out of the box (note I did update to latest firmware). First unit had a badly attenuated left speaker in powered mode (worked OK wireless). I received a replacement and this unit had questionable ANC (barely working I thought and periodically makes a strange noise when you move your head). The unit even more significantly kept dropping my phone calls (note I had head removal sensor off as I hear that was buggy and it still did it). I tried 2 other headphones I had and they did not drop the calls so I know it was the headphone. I received a third pair yesterday and I have none of the issues I identified on the other 2 pair so far.

Amazing sound, quality. Noise Cancelling good, but not great.

Quality is extremely high. You know you have bought some real good headphones. The style is a little dated. They looked like they are from the 80 or 90s. The Sound is high quality what an audiophile might expect. The Bluetooth is excellent, it connects immediately to anything, like they have glue or something. It is spectacular. Comfort is really bad for big heads like mine. The clamping pressure is high, I guess that is to improve the Noise cancelling. They are too small, they look like a toy or those early computer headphones from Logitech. That is very disappointing. I guess that is way they choose to save some cost to compensate the amazing built quality and sound. I returned the Focal Bathys for the same reason, too small. The head band gives me most of the problems being to small. They are extended at the maximum, but I feel the pressure at the top of my ears. The cups do not cover all my ears, because they sit a little high. The uneven pressure they exert make me nauseous and too much pressure that I keep fidgeting with them until I remove them. Sound is better than the Bathys. I am still sitting on the fence if return them or not. Remember the comfort is only bad for big heads.

Worth the money

Generally very pleased with these headphones in spite of the price. The only downside is the controls. Hard to actually figure what is turned on/off (noise cancelling mode, bluetooth connection and so on). Sound is pretty terrific. I'm hearing instruments I didn't previously hear in recordings I have been listening to for many years. Nice that they include an assortment of connection cables, adapters and plugs. Removes the need to go hunting around for the right adapter or cable.

I just want to say that I almost never give any five star reviews. Five star to me means perfect. Not much is perfect. I find that my enjoyment of these headphones surpasses any other headphones I have owned. Grado, Focal, Sennheiser, all sitting in my drawer. The ability to have such excellent bluetooth sound is extremely satisfying. When I am sitting around listening, I will often plug them in to my dac/amp and again have excellent music. They are like having two pair of headphones. I highly recommend!

Next Level Audiophile Sound

If you are asking the question "are these that much better than the Sony or Bose options?", my answer is absolutely a resounding yes. I use headphones almost exclusively for music and these are far and away better than the extremely good $350 ish options. Build quality is superb. They are heavy but weight is distributed well. There's a lot of tech in there. I think Sony's ANC is unbeatable and these don't quite hit that class leader to my ears. But ANC is very good. Sound quality is just on another level. Fullest Sound stage I've heard. They are just remarkable. I'd love to compare the Bathy's but my extensive research led me here. Extremely glad. If you are an audiophile you'll really like the Sony and Bose. You will simply be blown away by the Mark Levisinsons. Glad I bit the bullet and spent the money.

Excellent High End Wireless Headphones

I approached purchasing these headphones with a bit of trepidation. They are, after all, $999, roughly 3x my most expensive pair of wireless headphones (Sony WH-1000XM3) and 2x+ my most expensive pair of wired (Massdrop x Fostex TR-X00). That being said, I have long loved the product produced by Mark Levinson (own a No. 535 Integrated and used to sell their products in the early 90s), so I dove in. I needn't have worried at all. The fit and finish is what one would expect and the sound is incredible. Great detail and speed with high quality sources running APT-X and LDAC from my Samsung Galaxy S22 Ultra. Very flat response unless you use the ML app to boost your bass response (necessary on some "thin sounding" songs. The Battery life is outstanding. Have only charged once (when received) and still over 60% battery available with over 10 hours of active listening with ANC on. IF you're in the market for a great set of wireless headphones AND you are dabbling in the high end here, purchase with confidence. The only real detractor I have is the "On Head" detection is not good. Just don't use it and you're good to go.

ML 5909 Amazing!

My quest to find the best wireless headphones for me just stopped with my purchase of the ML 5909 from Crutchfield. Backstory first---I own the Focal Stellias which are in a league of their own thus I have a decent basis to work from when it comes to sound. Journey--tried the Focal Bathys--bright is my impression--compare to a Qled tv vs Oled--Qled is vivid and bright--Oled vivid but with more depth--the 5909 are like the Oled. Next--B&W P8 Bond edition --sounds great--probably in the middle of Bathys and 5909. I have used the 5909 bluetooth which sounded amazing. I have also used them wired using the new Chord Mojo2 connected via a silver dragon Usb-c cable from moon audio--this is connected to my Ipad to the Mojo 2--sound is unbelievable. Reference audio used was Danish National Orchestra via Youtube and Tidal music--their rendition of Good, Bad & Ugly along with numerous other Eastwood movies along with James Bond soundtracks will give the listener a great idea of how the headphones actually perform via multiple instruments. Synopsis--For me these are the best wireless headphones I have ever used!!! Packaging is first rate and everything to get started is included. In the future my hope is Apple will get rid of the Lightening port and replace with Usb-c thereby getting rid of the worthless doggles! Working with Crutchfield--fantastic experience and I would highly recommend working with them if you are in the market. Hope this helps someone who is trying to make a decision.

Wonderful if pricey headphones

After trying the PX8 and the Bathys, I ultimately picked these for a few key reasons. 1) Audio quality - Truth be told the Bathys and ML5909 were very close in terms of audio quality. I can imagine many people preferring the Bathys for its more mature sound that manages to handle hazier tracks with mid - high bleed and reign them in. I prefer the ML5909 for their more full and at times appropriately aggressive mid and high representation that really lets rock and female vocalists take center stage. The PX8 are great but a level below the two in my opinion. 2) True Passive Mode - Neither the PX8 or Bathys can be used power off while the ML can, which is a nice feature that I enjoy esp pairing them with my DAP (Hiby RS6) 3) Comfort - This is highly subjective but I found the ML to be the most gentle on ear feeling and didnt have unwanted jaw pressure that I experienced with the Bathys. The PX8 were solid but not as good as the ML 4) On-ear detection; While not perfect since the update it has been pretty reliable (it will stop after a short delay when headphones are removed, and resume quickly - unless they are off for two long and then they wont resume). PX8 are very very buggy currently. Bathys dont have this feature. 5) Respectable ANC; ML 5909 are slightly better than PX8, both are much better than the Bathys (tested using my speaker systems playing an engine rumble track). They also have the best passive isolation of all 3 on my head

If you love music, STOP here

So right out of the gate something to note. The ear detection is buggy. I returned my first pair of these as the music kept pausing regardless of the listening source, so I thought it had to be the headphones. Crutchfield as always was simply perfect with the return! Got the new pair and exact same issue. No way was this normal I thought! I decided to call Harmon Kardon (Parent company) directly as indicated on the Mark Levinson website. Not expecting much in the way of a solution I was super impressed when they told me to turn off the auto detect function and Voila...issue resolved!! I say all this to save you the effort and frustration, because in actual fact these headphones are nothing short of amazing. I am Crutchfield's perfect customer.. I am always buying headphones and earphones. I'm the moth to the light. I own Apple Air pods pro 1&2, Bose 700, B&W Pi7, Sony XM4s, B7W PX7s and many others . I also have several Hi Res sources to play from and this is what really separates the headphones. In wired and Bluetooth formats, these headphones are stellar. The nuanced sounds are absolutely incredible and easily match their wired non noise-cancelling luxury counterparts. These are the best of both worlds.In the airplane with noise, they sound fantastic, in a quiet environment, they are simply stunning. Detail across the sound spectrums is the sample all others are hoping for. Should head detection work better? Sure..but the sound is so good you won't miss it!.

The best-sounding Bluetooth headphone in the world

I've been spoiled for years by my audiophile-grade home headphone setup: The Fostex TH900 connected to a dedicated headphone amp. I love the rich, detailed sound of the TH900. The only problem with it is that it's bulky, with huge earcups and heavy-gauge wires, making it totally impractical for wearing on the go. So, I tried all of the high-end wireless headphones available in 2022, chasing that audiophile-grade sound. And the Mark Levinson No. 5909 is by far the best. Even over Bluetooth, it comes within inches of delivering the same level of listening pleasure that I get from pairing the TH900 with a dedicated amp. In particular, the tight bass is unlike any other wireless headphone I've heard. So why isn't this review 5 stars? Because as much as I love the No. 5909's sound, it's not a perfect headphone. There's audible hiss when no sound is playing, even with ANC disabled. A loud voice announces "Noise canceling off!" when you toggle the ANC. The carrying case is absurdly bulky. Last but not least, the ANC creates an uncomfortable feeling of pressure in my ears, which is an issue I had with early ANC headphones but haven't experienced with any other recent model. All of those flaws make me a little wary of endorsing this headphone for travelers, even for those who aren't deterred by the eye-watering price. (Try the Focal Bathys instead.) However, if you're looking for wireless headphones to wear at home or in an office, these are truly exceptional.

Quality worth every penny

I see in many reviews online a concern on the cost of these amazing headphones.ignore the price. Save up. Think of this.if you use it everyday, you should enjoy your headphones every time you pick them up. You should enjoy the look, feel, texture, comfort and get chills from the incredible sound quality.everyday, life is short. The price is a one time thing for something you will use and enjoy every day. It is so worth it. All aspects of these headphones are great. Solid, beautiful, expressive design, comfy, phone calls are perfect and the sound is the very best. The quality of the soundstage and imaging is unbelievable for Bluetooth. If quality sound and quality craft is your interest then these are your headphones. If your interest lies in big stupid looking aluminum ear muffs with the dumbest case on earth or, if your interest is in the "joy" of plasticky passionless touch tech then the 5909s are not for you. Run away, you are not ready for the quality of the no. 5909s.

Sound quality is excellent. A step up from my B&O H8s. These are not $3,000 wired headphones, but for travel I'm not aware of anything better in the wireless over-ear category with ANC. I had some initial problems pairing with my Astell&Kern portable media player. That was resolved by doing a factory reset on the 5909s - with the help of the very responsive tech support at Harman Int'l: Donald B.

I'm interested in products designed to last while also providing quality sound, and so far these headphones fit the bill. The build quality of the headphones is high. Aluminum and soft leather make up most of the external material selection, with the only plastic I can detect being the control buttons and the housing around them. I have a probably average head size, and the headphones fit snugly around my head at their tightest, so they could be a little tighter. In comparison to my 1st gen Sennheiser Momentum over-ear wired headphones, the cups for the ears are larger and provide actual over-ear wear compared to the Sennheiser's on-ear sizing. The case and all cables feel like quality as well. Sound quality rivals that of my wired Sennheisers in the wireless setting. It took my iPhone X a few tries to connect but since the initial pairing I've had no issues. I noticed a clarity in these headphones that is absent in my Sennheiser Momentum True Wireless 2s. Because of their impressive soundstage, there were multiple times I got the impression my music was playing from an external source when it wasn't. In public settings the wired sound quality is moderately improved, but honestly either connection provides music that sounds as good or better than any other heaphone I've used. The active noise canceling works well and there's a noticeable difference in modes. I had questions about the cost of these, but given what I wanted these headphones to do I will

The product is built well. Not too much plastic parts, good leather and stitching where it counts. The quality of the product is not in question. When making phone calls, I have had many people say that they can hear me SO Much better than any other time I use other in ear headphones. So far they only downside I have seen (for my taste) is that when I wear them during my walks around town, with every step I hear a thump (not a loud one, mind you but it seems like a thump sound with every step). It feels like I can hear my own footsteps and that is distracting while trying to do a walk about the park or around town. But stilling still and listening to it or on the plane, the sound is fantastic and the keeps the plane noice out better (or just as good as my BOSE headphones). Used it on 3 different flights and it's my go to for flights now or just sitting in the backyard and enjoying my book on tape while I eat or chill out.

Luxury ANC BT Headphones

The ML5909 headphones are exceedingly fine with luxurious fit and finish. I am a classically trained musician who does recording. If this perspective interests you, read on. On first listening (prior to burn in) my first reaction was that the sound was startlingly clear. Details hidden using most other earphones were suddenly audible. I would characterize the ML5909 sound signature as slightly emphasizing the treble. Prior to burn in, I heard a slightly tizzy treble with some undesirable resonance around the open E string of the violin as well as in vocals at similar pitches. Burn in improved this but it is still subtly present. The app allows some tweaking of the bass but no other frequency ranges. UltraHD tracks from Amazon Music were noticeably better compared to standard CD level. The best sound quality is with the supplied cable and USB-C/A adapter into my PC. My single disappointment is that I've experiened random and sometimes frequent (sometimes every few seconds!) music stoppages for no apparent reason. This occurs even when my iPhone is on the desk directly in front of me 1 ft away, playing tracks physically stored on my iPhone so the wi-fi connection should not be an issue. Unfortunately, Mark Levinson customer service couldn't help because they had no hands on experience yet (!) This music interruption problem will be a deal breaker, but if it can be solved, I would otherwise highly recommend the ML5909 as the Audiophile pick among BT ANC headphones. Update: I commend the support team at both Crutchfield as well as Mark Levinson in working with me to determine that there was a malfunction of the On-Head Detection system that seemed to cause the frequent music stoppages. A replacement 5909 now works as it should. I would add also that as I gain more listening time with the No. 5909, I remain enthusiastic about the remarkable clarity of the sound. That said I would characterize the sound signature as a little on the lean side, even with the Bass Contour enhanced. I find myself turning up the volume, sometimes >70% in order to gain the fullness of sound that I've grown to expect from recordings I'm familiar with. This need for higher volume setting is mainly with BT connections; wired connections seem to have a significantly higher volume, in line with amps I use, only requiring volume settings in the 40-50% range. Also, as pristine as the sound is over BT, the sound using the USB-C/A cable to my PC is substantially better - I would call it truly audiophile quality. And listening with the USB-C cable and with 1/4" adapter into a Sennheiser HDV-820 headphone amp, the sound is superb. Overall, the No. 5909 performance and features are phenomenal and I highly recommend it. I'm also highly appreciative of the well known customer service at Crutchfield as well as Mark Levinson, both of which definitely live up to their reputation.
