OmniSound Hub AI KROSS
OmniSound playing on five speakers at once: Sonos, JBL, LG TV, Harman Kardon and the PC

OmniSound Hub AI KROSS plays the same song on your Harman Kardon speakers and on every other speaker in your home - Sonos, Bluetooth speakers of any brand, the TV and its soundbar, the PC - perfectly in sync. It works with Aura Studio, Onyx Studio, Go + Play and Luna, over Bluetooth.

Why Harman Kardon owners use OmniSound

Harman Kardon speakers are made to look and sound great on their own; they don't sync with speakers from other brands. OmniSound removes that wall: it is one app that talks to every speaker the way that speaker already understands, and keeps all of them on the same beat.

How it connects to Harman Kardon

Pair your Aura or Onyx with the OmniSound hub over Bluetooth and it plays in sync with Sonos, the TV and the rest of the house. Gapless playback and crossfade keep albums flowing, and loudness levelling stops one song from being much louder than the next.

Tip: A Harman Kardon Aura on a desk next to the PC and a Sonos in the next room make a lovely two-room setup - calibrate once with the microphone.

The AI DJ plays your music on your Harman Kardon

Say what you feel like hearing - “90s dance for a summer party”, “something calm for a rainy Sunday”, “more like this song”. The AI builds the playlist from your own library (NAS, PC or phone), never invents songs, and starts it on the speakers you choose. While it plays, the lyrics scroll in time - translated into your language - and the AI tells you the story behind the song.

Set it up in three steps

  1. Install OmniSound on your Windows PC, Android phone or tablet, or LG TV - every device gets 7 days free with everything included.
  2. Open Speakers → Find devices and add your Harman Kardon (pair it over Bluetooth first), plus any other speakers you have.
  3. Run the one-click microphone calibration - and play. Every room hears the same note at the same moment.

FAQ

Questions

Which speakers can play together?

Sonos, any Bluetooth speaker or headphones, the TV and its soundbar (HDMI/eARC), the PC's own outputs and DLNA/UPnP network speakers - in any mix, at the same time. Speakers that only support AirPlay or Chromecast are not supported yet.

How does the sync work?

Each speaker has its own delay. OmniSound measures it - automatically with a microphone, or by ear with a slider - and delays the faster ones so all play the same moment. Clock drift is corrected while the music plays.

Do I need to pay for the AI?

No. Gemini, Groq and OpenRouter offer free keys and the app shows how to get one. If you already use Claude or ChatGPT, you can use those too. Your key stays on your device.

Where does the music come from?

From your own files: a NAS, the PC, the phone, a USB drive through the PC, or music servers like Plex, Jellyfin and Subsonic. Plus 50 000+ free radio stations, podcasts and free music. OmniSound does not sell or include music.

What does one licence cover?

One TV, one Windows PC and one Android phone or tablet. If you change a device, move the licence from the app or from the 'My licence' page.

What happens after the 7-day trial?

The radio and podcasts stay free. The library, AI, synced lyrics and music videos need a licence.

Does it work without internet?

Yes - your library and the speakers on your network keep playing. The licence is checked now and then, and works offline for a month.

Which TVs are supported?

LG Smart TVs with webOS 4 or newer (2018+). On other TVs, use the PC or the Android hub with the TV as a speaker.
