It's one of the most asked Sonos questions: "Can my Sonos play together with my Bluetooth speaker?" With the Sonos app alone, no - Sonos groups Sonos speakers, and a Sonos can only play one stream at a time. The mixing has to happen before the music reaches the speakers.
Let a hub do the mixing
OmniSound Hub AI KROSS is exactly that hub. It decodes your music once and sends it to every speaker in its own language: to Sonos over Wi-Fi (lossless WAV by default), to Bluetooth speakers as a normal Bluetooth output, to DLNA TVs and receivers over the network.
The hard part: Sonos is "late"
A Sonos speaker buffers incoming network audio - typically more than a second. A Bluetooth speaker is late by a few hundred milliseconds. If you simply play to both, the Bluetooth speaker is ahead and you hear an echo. OmniSound measures the Sonos buffer while it plays and delays the Bluetooth speaker by the difference. The one-click microphone calibration fine-tunes the rest.
Setup in two minutes
- Install OmniSound on a Windows PC (or Android phone/tablet) on the same Wi-Fi as your Sonos.
- Speakers → Find devices: add your Sonos and your paired Bluetooth speaker.
- Calibrate once with the microphone - done.
Volume stays separate for each speaker, so the kitchen can be louder than the living room. Group your Sonos rooms as usual in the Sonos app; OmniSound plays to the group.
