Seamlessly stream your favorite music to all Harman Kardon wireless HD audio products in your house

Stream your favorite classical music to one room while streaming rock to another. Multiple streams keep everyone happy.

Walk from one room to another and your favorite music will follow at the touch of a button.

Use the Harman Kardon app to stream your favorite music anywhere in your home. Control and configure your HD audio system wirelessly via  the app with no cable connection required.

Start a party and jump right in! When multiple songs are playing wirelessly, one button press cycles through them all so you can pick your favorite. One long press of the button starts party mode with every speaker playing back the same music. Room to room control made easy without the need to use your phone or tablet.

Unlike other wireless streaming systems, the Harman Kardon Omni 20 supports 24bit / 96kHz Studio Quality HD audio streaming.  Enjoy a superior audio experience, higher resolution than from a CD.

More music, more flexibility, more fun . With this feature, any app (for example iTunes Radio or Spotify) is part of the Harman Kardon whole home audio experience. Use Bluetooth and the Omni 20 will re-stream your music to other speakers in the house.

Group speakers together for an immersive same room wireless sound experience. A pair of Harman Kardon Omni 20 can be used as part of a stereo or multi-channel speaker system.

Connect your audio device or anything via Bluetooth or a 3.5mm mini-jack to your Omni 20 and the speaker will automatically translate the signal to Wi-Fi and stream its sound all over your house for a truly flexible whole home audio experience.

You can connect an OMNI 10 or Omni 20 to your TV set, and use them listen to the TV sound or movie soundtrack. You should use a wired connection from either a fixed line-level output on the TV, or from the TV’s headphone output. It is perfectly possible to add a second OMNI speaker for stereo use, through additional wiring, via signal splitters also known as Y-splitters. When re-streaming the TV sound wirelessly from one Omni speaker to other Omni speakers in the house, the audio signal will be slightly delayed compared to the video signal.

Rated 5 out of 5 by from The bass is unmatched I really wish it didn't have to be plugged in to function, but if you can get over that downside, this speaker is amazing. It looks classy and sounds classier.

Rated 5 out of 5 by from Why did I uy an Onyx again? Bought both this and an Onyx. This for me and the Onyx for my fiance and I to have on the go. (We live on the shore so we go to the beach a lot). This sounds exactly like the much more expensive Onyx leaving me to wonder if it's actually worth the extra $200. They're both amazing speaker. Bass is excellent (not overpowering) and mids and highs are clear. The app could be a better though, but we don't really use that much anyways.

Rated 5 out of 5 by from Great Sound! Just recently purchased the Harman Omni 20 for our home. There are several ways to connect but I connected via bluetooth. I tried connecting from my Macbook and Samsung phone. It has a nice full sound that carries throughout the whole room which was nice since we have an open floor plan. The quality of the sound does not change even when you increase the volume. The only thing I did notice was when I connected to the laptop, there was some static initially (for a split second) and then the sound is clear. Note: The description says it's wireless but you actually need to plug in. There is no battery option.

Rated 5 out of 5 by from Amazing Sound out of a small, smart device I have tried out so many little speakers and every time the sound is disappointingly thin without enough bass. With the omni 20's I finally found what i was looking for. Great balanced sound, clear with fantastic bass. You would think the music is coming out of a much bigger speaker set. I love the convenience of playing it from my computer or iPhone through bluetooth. Once you set it up it will go to sleep after you stop playing music and will automatically reconnect once you start again. No need to press any buttons. Highly recommended.

Hello, once I have paired two units via the App, can I stream directly over bluetooth without using the App to both speakers in stereo type mode? Or will both speakers only be linked when using the App?

Asked by: swisspete
You can stream directly over Bluetooth without using the app only if you intend to use one OMNI 20. The app has to be utilized in order to link 2 OMNI 20's.

Hello, how does the sound of the omni 20 compare to my onyx studio 2? Thanks.

Asked by: swisspete
Both speakers have a rated power of 4x15W. This means the OMNI 20 has a very good bass and sound quality which is comparable to ONYX STUDIO 2.

Hello, I am having difficulty turning the speaker off. I even  disconnect my device and I still cannot  turn off the speaker. I tried holding down the power switch and nothing happens.  I manually have to unplug the speaker. thanks for your time 

Asked by: Becca
The OMNI 20 cannot be turned off completely while connected to a power source. It does not have a power button or switch. If it doesn't go on standby mode when not in use, please submit a case at and the Customer Service team will be more than happy to assist you.

Hallo, ist deezer in die hk-app eingebunden? Sodass unterschiedliche Musik auf dem Adapt und Omni20 gestreamt werden kann?

Asked by: Chris22
Hallo, Deezer ist schon im Controller App integriert, allerdings, Sie haben nicht die Möglichkeit, unterschiedliche Musik auf unterschiedliche Omnis von denselben Gerät zu streamen. Dafür bräuchten Sie noch ein zweites Quellgerät dazu.

I bought two of the Omni 20 speakers, how do I know when the unit is charging and done charging? I must be a moron because I have gone through the instruction booklets several times....and find nothing related to this question. Thanks!

Asked by: mrjiggs777
Unfortunately, the OMNI Series speakers are not portable speakers. They need to be constantly plugged in to work.

Does the app work with Apple Music service via WiFi or do you have use Bluetooth?

Asked by: Jeff B
Unfortunately, the OMNI series speakers are not compatible with Apple's Airplay feature which enables iTunes to play audio to speakers via WiFi. You can use any 3rd party music players/service with the OMNI Speaker system through Bluetooth and AUX connection ONLY.
