About the Sony LF-S50G

A wireless kitchen aide — and so much more

“OK, this one's going in the kitchen.” That's what I said when I got the Sony LF-S50G home to try out. Built-in Google Assistant voice commands meant I didn't have to touch it with sticky hands while making bread. I just told the speaker what to play. And the 'S50G's simple gesture control meant I could adjust volume, even while the sound of garbage disposal made voice commands impossible.

Sony LF-S50G

“OK, this one's going in the kitchen.” That's what I said when I got the Sony LF-S50G home to try out. Built-in Google Assistant voice commands meant I didn't have to touch it with sticky hands while making bread. I just told the speaker what to play. And the 'S50G's simple gesture control meant I could adjust volume, even while the sound of garbage disposal made voice commands impossible.

The speaker's compact, splash-proof design let me place it close to the sink. And I could even remove the speaker's grille and wash it if things got a little messy. Oh — and it had great sound, too.

Innovative design

The LF-S50G achieves its spacious, 360° sound in a unique fashion. One 2-1/16" driver and one 1-7/8" driver face each other, with a two-strand diffuser between them. This blends the sound and spreads it out in all directions. A bass reflex port reinforces the low register for an even stronger sound.

Google Assistant for the win

The LF-S50G has Google Assistant built in. You can tell it to play a favorite song, give you the weather, and more. Google Assistant also gives you easy voice control over compatible smart home devices from Wemo, Philips Hue, Samsung SmartThings, Nest, and others.

Music options galore

Stream music over your Wi-Fi® network through the LF-S50G from services such as Spotify®, TIDAL, Pandora®, Google Play Music, TuneIn, and iHeartRadio.

The S50G also has Bluetooth 4.2, so you can stream near-CD quality music directly from your phone or tablet with any audio app you choose.

Multi-room audio? Yes, please!

You can also make the LF-S50G part of a wireless whole-house audio system using your Wi-Fi network and other Chromecast built-in speakers. Setup is simple with the Google Home app. And once you've grouped your speakers, you can control them with voice commands.

Other cool features

Indicator lights let you know when the S50G is listening. And the mic on/off button on the base lets you decide when you want the speaker to listen. I didn't have to ask the LG-S50G the time — there's a four-digit clock display right on the front, behind the grille. Placing the LF-S50G on our bedroom nightstand was my second choice.

Roon-compatible for serious music lovers

The S50G is also compatible with Roon, a subscription digital music player you download to your smartphone, tablet, or computer. It gives you multi-room audio playback for all your Chromecast-compatible devices and more. Roon accesses your digital music collection from your iTunes library or NAS drive. It also works with your TIDAL subscription. Roon lets you do deep dives into your music, showing artist bios, photos, reviews, and lyrics. Roon can also suggest other artists and songs based on your selections, making it easy to discover new music you'll enjoy.

Product Research


360° Omni-Directional Sound: The Sony LF-S50G wireless speaker's 360° omni-directional design lets you hear the same great sound from anywhere in the room. Enjoy clear sound and rich bass in every corner of the room thanks to a two-way facing driver design, two-stage diffuser, bass reflex duct, and 18W (Peak) amplifier.

  • Two-Way Facing Drivers: The two drivers face outwards in the center of the speaker for maximum sound coverage.
  • Two-Stage Diffuser: A diffuser spreads sound throughout the room in every direction, for wall-to-wall audio.
  • Bass Reflex Duct: Immerse yourself in bass with the bass reflex duct, which controls resonance speed and frequency.

Splash Proof (IPX3): The Sony LF-S50G wireless speaker can handle a little water, thanks to an IPX3-rated splash proof design. You can even take the cover off and rinse it under the tap. IPX3 enables water splashing against the device from a vertical angle of 60° for a maximum of 5 minutes.

  • The LF-S50G is not water proof and should never be submerged in water. It is also not marine certified and should not come in contact with salt water.
  • When the speaker grill is removed from the speaker, the speaker does not meet the IPX3 water resistant specifications.

Dual Band WiFi: To enjoy Chromecast Built-In & Google Assistant, you will need to connect the Sony LF-S50G to your wireless home network. The LF-S50G is equipped with dual-band (2.4GHz/5GHz) WiFi (802.11 a/b/g/n) for a high-performance wireless network connection.

Google Home App: Use the Google Home App for Apple iOS 9.1+ and Android OS 4.0.3+ to connect the Sony LF-S50G to your home's wireless WiFi network, as well as setup the Google Assistant & Chromecast Built-in from your compatible Apple iOS or Android device. You also get to configure compatible apps within the Google Home App, plus adjust other various settings.

Built-in Google Assistant: The Sony LF-S50G is powered by Google Assistant and features two integrated omni-directional microphones. You can use a wide variety of voice commands to control the operation of the wireless speaker in conjunction with Google Assistant. Just say a voice command to the speaker. Then, the speaker will perform the Google Assistant activity associated with that particular voice command. By simply saying "Ok Google", the LF-S50G can help perform tasks like playing a favorite song or controlling smart home devices; checking the latest weather, traffic, and finance reports; as well as finding out the latest sports scores. Thanks to Google's robust search engine, the LF-S50G with Google Assistant is ready for all your questions and commands. Click here for all the latest voice commands.

  • Music & Radio: Use your voice to select, play, and control music from compatible Chromecast Built-In music services - like Tidal, Spotify, Pandora, TuneIn, GooglePlay Music, YouTube Music, iHeart Radio, and more.

You can even create your own voice commands for the Google Assistant on your Apple iOS or Android device using IFTTT (If This, Then That).

Also, use voice commands to set alarms and timers for things you need to do. Use Google Home and Google Calendar to get information about an event or get your schedule for the day from Google Calendar - using only your voice. Currently, you will only hear events from the main calendar associated with the Google Account used to set up Google Home. You can't add events to your Google Calendar using your voice. You can even use Google Assistant and Gmail to get status updates on your upcoming flights.
  • Alarms & Timers: Set, check, cancel, stop, and snooze multiple recurring alarms. Never run late or miss a flight or meeting. You can set and manage alarms with just your voice.

Set, pause, check, resume, and cancel timers.

  • Get Answers: The LF-S50G's built-in Google Assistant helps you find answers for many of your daily questions through the Google search engine - including calculations, translations, unit conversions, nutrition, dictionary, finances, facts, and more.
  • May of these features must be enabled from the Google Home app before they can be used. Also, make sure the speaker has the latest firmware update.

  • The Sony LF-S50G does not support Google Assistant hands-free calling.

It says bluetooth and wireless but when I unplug the AC power adapter it fails to function, so is it not portable?
[ Isaac  Jun 04, 2019 ]

It doesn't have a rechargeable battery. It's portable but you are tied to an outlet. I didn't realize that also when I ordered it.
