Take your music to every room, and outside

Polk Audio Omni S2 Rechargeable wireless powered speaker

The Omni S2 Rechargeable wireless speaker is weather-resistant, so you can stream your favorite music outside on your deck or patio.

Play loads of music wirelessly with your smartphone or tablet

The Omni S2 Rechargeable speaker offers lots of ways to listen to music. The free Polk Omni app for Apple® and Android™ is your hub for accessing music stored on your smartphone or tablet. You can also stream music from networked computers and music servers. If you're one of the millions of Spotify® Premium subscribers, Spotify Connect lets you access all your favorite albums and playlists. There's built-in support for Pandora® Internet radio and SiriusXM. Plus, you can choose from over 37,000 free Internet radio streams, for a nearly endless supply of music and other programming.

Wireless setup and control

The S2 Rechargeable is easily set up and controlled via Wi-Fi® with your smartphone or tablet. Adding speakers is as simple as plugging them in and tapping a few buttons. In just minutes, you can have music playing throughout your house, without running a single wire except plugging them into a power outlet.

Play-Fi® turns every smartphone into its own music system

The key to the Omni S2 Rechargeable's wireless music capability is Play-Fi. Developed by audio innovator DTS, Play-Fi allows you to send the same song to multiple speakers, play a different song in every room, or let each member of the family control speakers independently with their own device. Play-Fi can transmit lossless audio at CD quality to up to 16 speakers or components on your network. Best of all, the S2 Rechargeable can work with other Play-Fi speakers from other manufacturers. That means you can mix and match different brands of wireless speakers, offering more flexibility than closed systems.

Sound you'll enjoy as much as we do

Polk Audio speakers have long been favorites with our customers, as well as our employees. The Omni S2 Rechargeable's sound is just what we've come to expect from Polk — smooth, clear, and well-balanced, with tight bass that doesn't overwhelm and detailed high frequencies that don't pierce your ears. Just what you need to turn a day of doing chores around the house into a music-charged pleasure.

(18 Reviews)

Great for my application

James from Livonia, MI on 12/10/2017

Crutchfield Customer Review (What's this?)

I bought this speaker to replace an existing whole house sound/intercom system. If it works well I will buy more. Setup was very easy and the sound is very good and as good as my other fixed Polk surround sound speakers. It will be paired with a Soundbar eventually, and the plan is to have whole home sound. A couple of minor issues I have is that the documentation really doesn't tell how to shut down the speaker. I did figure it out. The app is easy to use with setup and update the firmware. The Play FI works well and did it's update. I moved around the house and the speaker never quite or lost sound quality. I played with going from wifi to bluetooth back and forth and it worked as expected, both using all devices (Laptop, Phone, iTunes, online etc...). I wish there was a volume display of some sort, but not necessary. I will buy 1 or 2 for other rooms in the future.

Pros: Easy Setup both Polk & Play Fi Bluetooth works great

Cons: Documentation could be a little better detailed.

Mary from Georgetown, TX on 9/20/2017

Crutchfield Customer Review (What's this?)

This speaker sounds great and was fairly simple to set up. I also own the Omni soundbar. I love that the speaker is portable as I plan to use it on my patio. I put 4 stars because I wish it had an on/off button and I wish the omni app was more user friendly. The first speaker we received would not properly set up to wi-fi, but Crutchfield promptly replaced it and the new one set up fine.



Love this new addition!

Chet from Ft Mill, SC on 5/7/2017

Crutchfield Customer Review (What's this?)

This speaker has great sound. It's been a great addition to my Definitive sound bar and sub. Gives the area a more complete sound now. Does really good on its own too. I can say that a single S2 does lose its sound power outside by itself. It does have great wifi range. I can use it on my back porch with no problem. The front porch can drop on occasion. The Bluetooth connection and battery is what really sets this speaker apart from the similar ones.

Pros: Wifi + Bluetooth Battery to take it on the road Certainly the most flexible I've used

Cons: Sound is great inside. For a it to be great outside as a stand alone, I think a round/tubular shape would work better.

Promise...but not delivery.

SG from Helena, MT on 4/26/2017

Crutchfield Customer Review (What's this?)

The app that you have to use with this speaker is marginal at best... which really limits this product's usefulness. I am not the first person to reach this conclusion. The speaker will shut off randomly when listening, which is annoying. It will also disconnect from your router sporadically. On a positive note, Polk tech line people were courteous and as helpful as they could be, the product needs development. Crutchfield was great about the return. Polk needs to sit down with their app developers. Tried Bluetooth but didn't work too well from even 10 ft. from source.

Pros: Solid, well built speaker.

Cons: Disconnects from router and powers down randomly. Companion app needs help.

Disappointed by Crutchfield

jeffrey from Springfield Gardens, NY on 4/23/2017

Crutchfield Customer Review (What's this?)

Received open box items from Crutchfield instead of factory sealed. Should have been stated in order description and price reduced. On air update did not work. Need to download update to flash drive and manually update thru usb port.

Pros: Sound quality good

Cons: Needed manual update thru USB port

Crutchfield response on 4/26/2017 We appreciate the review and apologize for the error. We've refunded Jeffrey for the trouble. Our warehouse is also reviewing the situation to prevent this from happening in the future.

To much bass, loses charge

Kay from OH on 4/17/2017

Crutchfield Customer Review (What's this?)

There is to much bass produced by this speaker. I tried various locations and there is still to much bass. It would be nice to be able to adjust the bass, treble etc. Also, the speaker loses the charge when turned off. I charged the speaker then turned it off. A day later I tried to turn the speaker on and it was dead. I tried this several times with the same result.

Pros: Connectivty

Cons: Bass, charge loss

Crutchfield response on 4/19/2017 Kay, we're sorry you're having problems with your speaker. Whenever you encounter a problem with anything you purchase from Crutchfield, please contact our tech support team right away. They can help you solve the problem or set up a return within 60 days of purchase. We forwarded this review to our Technical Support team for follow-up. Lifetime tech support comes with every Crutchfield purchase.

Good sound - doesn't connect

Jarad from Ft Collins, CO on 4/11/2017

Crutchfield Customer Review (What's this?)

I love Polk audio and am impressed with the sound this small speaker produces. The Omni S2 feels well built and is solid. Downside is that it won't connect to my wifi so it is only being used as a Bluetooth speaker at this point. I've tried to troubleshoot connectivity issue with no sucess. Not sure it is going to stay if I cannot connect to the unit via wifi.

Pros: Good sound and good build quality.


Crutchfield response on 4/12/2017 Jarad, we're sorry you're having issues with your wifi connection. If the problem continues, please reach out to our tech support team. They can either help get the speaker working the way it should, or possibly return it for an exchange or refund.

Crutchfield Customer Review (What's this?)

Great sound. Solid battery life. Integrates well with wireless and bluetooth



Love the rechargeable wireless speaker

Peter from Ft Lauderdale, FL on 9/25/2016

Crutchfield Customer Review (What's this?)

I bought this to extend the coverage from my Tiki Hut to the screened porch and have the same music playing all over the back yard and out to the dock. I can even bring it inside so guests raiding the 'fridge don't lose a beat. When it arrived (really fast) I was worried that the sound wouldn't be very good from such a small speaker - boy was I surprised. I'm a big fan of polk speakers and have them in my home theater, tiki hut and now portable. The bass feels big and strong and the sound fills up the room and porch without sounding forced or "tinny." The app could use some work - not as easy to work as other music apps and takes some work to set it up. It allows me to use my Omni A1 and the S2 to stream the same music for parties and general everyday listening. If the APP worked better this would definitely get a 5-star review. Hopefully Polk can make the App work better so I can upgrade my review. Will likely buy more of these speakers to further extend my music.

Pros: really surprising sound - sounds like a much bigger speaker. It's easy to take with you where ever you go and expands my outdoor music coverage

Cons: set up and controlling is harder than my Yamaha App for my receiver

Polk Audio Omni S2 Rechargeable

Ernesto from San Juan, PR on 6/5/2016

Crutchfield Customer Review (What's this?)

I have to say I'm super pleased for choosing the omni rechargeable speaker S2. The fine sound with good bass convinced me I did a good buy. I have in the bathroom and heard simply powerful !!!

Pros: Very good bass

Cons: so far I have not seen cons


David from Mountain View, CA on 5/30/2016

Crutchfield Customer Review (What's this?)

I was excited to try the device and was hopeful it would replace my current outdoor solution. Unfortunately, this was not the solution I was hoping for. First, I found the wifi would cut out inside requiring me to retransmit the audio to the device. Second, the device struggled to get a wifi signal outside by the pool, which rendered it useless. Sadly, it lasted a day and found its way back to Crutchfield

Pros: - wireless - battery - good sound

Cons: - wifi cuts out - short range - needs an EQ

Jerry r from Englishtown, NJ on 4/14/2016

Crutchfield Customer Review (What's this?)

Only have it about a week but seems great & Crutchfield is great to deal with.wonderful tech support.

Pros: Sounds great & the portability is super

Cons: Cannot find anything wrong or negative.

Terrible App

Michael from alexandria, VA on 2/26/2016

Crutchfield Customer Review (What's this?)

Good sound and portable. Horrible App. Constant connection issues. No EQ. No You tube, No free Spotify.

Pros: Portable, Good sound. Two connection types: wireless and line.

Cons: Terrible App. Connection issues. No free Spotify, no You tube. The speaker/app is always forgetting itself. It makes you set up as a new speaker almost every single day it is used. Using iPhone and iPad to connect. Must download two apps. One for the music and the other for software updates, etc. I will ask Crutchfield my options, but I have given this speaker a fair shot for 6 weeks. The portability and sound are good. Very disappointed. Maybe works better on Android.

Great sound for size, and portable

MaxC from South Carolina on 12/29/2015

Crutchfield Customer Review (What's this?)

I bought this Polk Omni S2 rechargeable to go along with a Polk Omni P1 I have hooked up to my main sound system for Play-Fi. I reviewed that separately and gave an overview of the setup. The S2R is a great sounding small speaker with a lot of bass for its size. So much bass that it is almost a drawback because you might want to put it standing up in a corner as pictured, but that makes it even more bassy. It actually sounds better in a small space like a bathroom if you I put it in the middle of the counter. I had a few connectivity woes when getting started. Polk was awesome and sent me an Asus gigabit router fo free and so far I've had no troubles and got into the modern era with a dual band router. This speaker is awesome to take out on the porch or deck etc. Actually sounds better when it has some breathing room. I am getting at least the advertised 10 hours off charger. Important to note that if the S2R is "Primary" in a Play-Fi speaker "group" and then the battery dies it will take down the whole group. Yeah, buzzkill. So just make sure if you have multiple zones to add the rechargeable/s last when setting up the speaker group. Bought another one for my brother for xmas and it sounds fantastic on their screen porch.

Pros: *Sounds pretty damn good for a small speaker *Full spectrum sound with great bass response for its size *Affordable *Great battery life *Good looking

Cons: *Sometimes get a vibration/buzz but not sure it's the speaker *I second another reviewer--All about dat bass, especially when in a corner--which is sometimes the optimum place for space reasons. EQ in Polk Omni Utility please!!!

Great Product

Reed from Virginia on 6/21/2015

Crutchfield Customer Review (What's this?)

Great sound. Very easy to set up. Particularly like the fact that I can stream thousands of internet stations, Pandora, and Sirius XM. The base is great, and I like the battery so I can take out on the deck and near the hot tub outside.

Pros: Battery, Wi-Fi, Pandora and Sirius XM.

Cons: Still trying to figure it out.

Omni S2 Rechargeable Wireless Speaker: The Omni S2R is a compact wireless speaker that lets you put Polk's widely respected signature sound in any room of your home, or outside on the porch, patio, or deck. The Polk Audio Omni S2R uses two 2" full-range drivers powered by a two-channel Class D amplifier, while the two 2" passive radiators create a fuller bass response. The Polk Omni S2R features a rugged ABS cabinet that is weather resistant for the casual outdoor use. Infrequent and/or accidental rain and sun exposure should not harm the speaker.

Omni Series: The Omni S2R is part of Polk Audio's Omni Collection, a series of wireless products that allow you to control what you want to listen to from your smartphone, tablet, or computer and stream it wirelessly to any room. You can start with one Omni series wireless product and then add more throughout your home or office.

DTS Play-Fi Wireless Technology: Polk Audio's Omni series collection of wireless speakers employ DTS Play-Fi wireless technology for wireless sound that is reliable and high-quality. DTS Play-Fi combines DTS audio and WiFi (802.11 g/n; 2.4/5.0GHz) wireless technology to wirelessly stream high-definition "lossless" audio with no impact on sound quality. DTS Play-Fi will stream pure, bit-for-bit, lossless audio, for uncompromised quality sound; up to 16-bit/48kHz. DTS Play-Fi has a range of up to 100' from your wireless router.

Note: All DTS Play-Fi enabled products work seamlessly together, so there's no hassle adding more speakers, or choosing more than one audio brand (like Definitive Technology, Phorus, Wren, etc..) in your home.

Simple Setup: There are two methods for connecting the DTS Play-Fi speaker to your home network. You can perform WiFi setup via the Polk Omni App on your Apple iOS/Android mobile device or Windows PC (this setup allows you to connect multiple Play-Fi device at once to your network). You can also use the WPS button on the speaker if your wireless router supports WPS (this setup only allows you to connect one Play-Fi device at a time to your network).

Polk Omni App: Download the free Polk Omni App onto your Apple iOS (6.0+) device, Android (2.2+) smartphone/tablet, or Windows (7/8) PC for easy and convenient management of your music from your mobile device or computer. From the app you can initially set up the Omni wireless speaker system, as well as add, link, and control all your Omni and DTS Play-Fi speakers. You'll be able stream music directly from the system's built-in music online services, or music on your mobile device or PC to multiple Omni series and DTS Play-Fi enabled speakers through out your home. The app lets you browse your music by artist, album, genre, or title; and provides album art. You can choose to play the same music in each zone or a different song in each room.

Variety Of Sources: Polk Audio's Omni series wireless speaker collection supports a variety of music sources.

  • Mobile Device (Apple iOS + Android): You are able to wirelessly stream your music files from your music library on your Apple iOS (8.0+) or Android (4.0+) device to the Polk Audio Omni speaker system through the free Polk Omni app.
  • Online Music Services: From the DTS Play-Fi app on your mobile device or computer, you can share and listen to Pandora, Spotify Connect, SiriusXM, TIDAL, Amazon Music, iHeartRadio, Napster, and Internet Radio. While the DTS Play-Fi app is free, not all the online music services are (subscription & purchasing fees may apply).
  • Computer Audio: The Polk Audio Omni series wireless system is DLNA compliant for playback of various music files stored on your Windows PC (7/8) or DLNA-certified NAS drives connected to your home network. MAC OSX computers and laptops require third party software to be visible on the network (Twonky, Plex, Servio etc.) as they do not support DLNA. Use the free Polk Omni app on your mobile device or computer to access these music files.
Supported Music Files: The Polk Audio Omni series wireless system and DTS Play-Fi support music formats such as MP3, AAC, FLAC, and WAV. The system will recognize music files up to 24-bit/192kHz and wirelessly stream these files at up to 16-bit/48kHz (CD quality sound). Some down-sampling may occur to ensure virtually lossless distribution throughout a home network.

Critical Listening Mode: For those who wish to hear high resolution audio as originally intended, Critical Listening mode will enable native rendering of high resolution files up to 24-bit/96kHz, with no down-sampling or network synchronization adjustment. In this way, audio files retain their original audio integrity. Critical Listening Mode is only available on one DTS Play-Fi speaker and not supported for multiroom audio distribution.

Maximum Number of Rooms/Zones Supported: You can play the same source in each zone or a different song in each room. Eight separate wireless source devices (smartphones, tablets, etc.), each with its own source, are supported simultaneously and any wireless source device can stream to eight DTS Play-Fi playback devices. Due to the bandwidth limitations of most wireless networks, no more than 16 wireless DTS Play-Fi products on a single WiFi network at one given time is recommended.

Stereo Pair: The Polk Omni app lets you link two Polk Omni S2R speakers together to create a stereo image with discrete left and right speakers. This is perfect for larger spaces or for the enthusiast who wants a stereo image. After you setup a stereo pair, the two Polk Omni S2R speakers will show up as one "Speaker" under the speaker tab of the Polk Omni app.

Wireless Surround: You can use a pair of the Polk Omni S2R wireless speakers as rear surround speakers for the Omni SB1 Plus soundbar speaker system. Simply update the speakers' firmware using the Polk Audio Utility app (for iOS & Android), followed by a single update to the DTS Play-Fi software using this same app. Once updated, setup is simple and can be completed in minutes. It is highly recommended that the wireless rear surround speakers be placed on the 5GHz band of a dual band AC router.

Aux Input: A 3.5mm auxiliary input lets you connect and play music from other audio sources, such as a portable CD player or MP3 player with an audio output or headphone output jack. This input can only be played back at the speaker location and cannot be used for a multiroom application.

Rechargeable Battery: The Polk Omni S2R uses a lithium-ion rechargeable battery which can last up to 10 hours on a full charge at moderate listening levels. The included AC power adapter charges the built-in battery and can be used to power the wireless speaker.

Mounting Options: The Omni S2R can sit horizontally or vertically on a table-top.
