Which devices are compatible with the VOL20?

The VOL20 is compatible with digital audio sources that support USB or Bluetooth peripherals, including PCs, Macs, laptops, mobile phones, tablets, digital audio players, and streamers.

Can VOL20 be used with Apple TV?

VOL20 can be used with Apple TV, but the connected TV must support HDMI CEC functionality.

Why can't my computer detect the VOL20 in pairing mode?

If the VOL20’s blue light is solid instead of flashing, it's connected to another device. Delete the VOL20 from any previously paired devices, then try connecting again from your computer.

Why does Bluetooth disconnect after PC restarts, though wired works fine?

Bluetooth reconnects automatically. If the USB is connected, it takes priority. Disconnect the USB cable to allow Bluetooth to reconnect.
