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.

Please help - when trying to play my TV through the speakers with a 3.5mm jack connection there is a lag between the image and the sound - How can i prevent this from happening ? Thanks

Asked by: Jon01
Hi Jon01, Thank you for your question. When using the speakers, there will be a small delay between image and sound. Many TV's have the option of adjusting "Lip-sync", and if your TV have this feature then i would try adjusting it and see if you can get sound and image to be in sync. If you need further assistance, please contact our helpdesk.

Hello. I have some problems with the app and the wi fi connection. It plays one song and then I'm not able to play another one. It starts searching and doesn't play the next one. Thanks

Asked by: Ignacio
What you are experiencing is not normal. If you’re playing a song from an album and the next song doesn’t play, the speaker must be acting up. Please try one of the following steps to possibly fix the issue. -Remove your pairing from your phone/table and reset your OMNI speaker and repair again. -Check and download the latest software of the app and speaker If none of these things work, please submit a case at www.harmankardon.com/contactus and the Customer Service team will be more than happy to further assist you.

Bonjour, Je suis intéressé par votre enceinte Omni 20 mais je n'arrive pas à comprendre si elle fonctionne en Wifi (pour une écoute à partir d'un iPhone en passant par le Wifi domestique) car je ne suis pas intéressé par du Bluetooth. Merci

Asked by: Guillaume05
Bonjour, Nous vous remercions pour l'intérêt que vous portez à nos produits. Par l’intermède de notre appli vous pouvez connecter l'enceinte Omni 20 à votre réseau Wi-Fi et après utiliser l'appli pour diffuser de la musique stockée sur votre iPhone vers l'enceinte ou en utilisant l'une des applications intégrées dans notre application (Deezer, Tidal, Qobuz, SHOUTcast). La diffusion de musique se fera en Wi-Fi en utilisant notre appli. Une précision s'impose ici: si vous avez téléchargé de la musique pour à écouter hors ligne, celle-la ne pourra pas être diffusée depuis notre appli. Bluetooth est également une bonne fonctionnalité d'avoir, au cas où vous voulez diffuser de la musique depuis d'autres applications de musique. Pour plus de renseignements, veuillez contacter le département Service Client.

Asked by: MIHELE
Hi, Thank you for your question. Sorry to hear about the issue you are facing with the OMNI speaker. If the reset button do not work, then i would strongly suggest going back to Place of purchases and ask for either to get a new one or warranty repair. If you need any other further assistance, you are more than welcome to contact our helpdesk.

With the new Omni+ range including Google cast and Spotify, will I be able to build my old omni speakers into a WiFi network to play these new services?  To do this will I need to buy a new omni+ speaker and/or Apt to link to existing tv stereo system?

Asked by: Patric
You will need to buy new OMNI+ speakers to enjoy the added streaming services. You will be able to link your existing OMNI speakers with an Omni+ speaker playing Spotify Connect or Google Cast and enjoy the music on all the OMNI speakers in your home.
