With Optical passthrough, TV audio can play through an OPT soundbar and Bluetooth headphones simultaneously. HDMI ARC / eARC passthrough is NOT supported.

5. Vianmääritys
5.1 Kuulokkeiden uudelleenkytkeminen
Typically, you won't need to re-pair your headphones with the Oasis Plus 2 every time, as they should automatically reconnect when both devices are turned on. If they don't, here are a few things you can try:
- Solution 1: Disconnect from Other Devices. Make sure your headphones aren't already connected to something else, like your phone or computer. You can turn those devices' Bluetooth off, manually disconnect, or move out of range from them.
- Solution 2: Initiate Reconnection (Transmitter). If they still don't connect, press the Oasis Plus 2's pairing button (either "1" or "2" depending on which headphone you're trying to reconnect) once to manually initiate the reconnection process.
- Solution 3: Initiate Reconnection (Headphones). The last thing you can try is initiating reconnection on your headphones as well. You can check your headphone's user manual for directions on how to do this if necessary.
