Give a compatible USB audio host a wireless connection.
Connect a supported Bluetooth headset or speakerphone to a compatible USB host with a compact dedicated audio adapter. B20 uses its own pairing button and indicator, making a supported audio setup easier to identify and reconnect.

Know what connects where.
Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
A small adapter with a specific job
B20 is intended for supported Bluetooth audio devices, including documented AV Access speakerphones. It should not be treated as a general-purpose Bluetooth radio for keyboards, file transfer and every Bluetooth accessory.
Pair from the adapter
Plug it into a compatible USB audio host, put the audio device into pairing mode, and use the B20 pairing button as described in the manual. The LED indicates the pairing and connection state.
Keep the radio path simple
An unobstructed range up to 8m is specified. Metal enclosures, crowded USB hubs and nearby radio equipment can affect the connection, so test the intended placement with the actual headset or speakerphone.
Make sure it fits your setup.
USB audio support
A PC, console or TV must support the required USB audio device operation. A USB port used only for power or storage does not establish audio compatibility.
Supported audio device
Check the Bluetooth headset or speakerphone compatibility. Do not assume proprietary gaming-headset radio systems use standard Bluetooth audio.
Select the output
Choose the connected USB audio device in the host or application’s sound settings, including the microphone where supported.
From unboxing to connected.
Match your devices
Check connector types, signal direction and the required output mode.
Make the connections
Follow the labelled input and output ports for the selected arrangement.
Select your settings
Choose the source, layout or pairing mode supported by this model.
Confirm operation
Check the image, sound and controls with your actual connected equipment.
