Frequently Asked Questions

Q: Can this Bluetooth audio adapter work with wireless headphones and a CD player?

A: Yes! Simply plug the B6 adapter into your CD player's 3.5mm audio output port and switch it to Transmitter mode. It will then stream audio wirelessly to your Bluetooth headphones or speakers within a 33-foot range.

Q: Does the Bluetooth transmitter/receiver need line-of-sight to maintain a connection?

A: No, line-of-sight is not required. The Bluetooth 5.0 signal can pass through walls and obstacles up to approximately 10 meters (33 feet). You can place it behind a TV or inside a cabinet and it will still connect reliably.

Q: Will this Bluetooth adapter work with Apple AirPods?

A: In most cases, yes. AirPods use standard Bluetooth pairing protocols, so as long as they successfully pair with the B6 adapter, they will work. Put your AirPods in pairing mode and press the button on the B6 to connect.

Q: Can I use this adapter while it is charging?

A: It is not recommended to use the adapter while charging, as this may affect audio quality. For the best sound experience, charge the device fully before use.

Q: What is the difference between Transmitter and Receiver mode on this Bluetooth adapter?

A: In Transmitter (TX) mode, the B6 takes audio from a wired source (like a TV or CD player) and sends it wirelessly to Bluetooth headphones or speakers. In Receiver (RX) mode, it receives audio from a Bluetooth device (like your phone) and outputs it through a wired speaker or stereo system. One button switches between the two modes.
