Transmitter Mode: Quick Setup & Connection Guide

Plug & Pair
Connect B03 to power, then use AUX/RCA/Optical to connect it to your TV. Set B03 and your Bluetooth headphones/speaker to pairing mode.

Pairing Success Tip 1
For a stable connection, please disable your phone’s Bluetooth prior to pairing to avoid potential interference.

TV Settings

How can I reduce audio delay while watching TV?
Use Bluetooth headphones/speakers or Bluetooth receiver that support aptX Adaptive or aptX Low Latency to reduce audio delay. Standard Bluetooth devices may cause noticeable audio and video synchronization delay.
How do I adjust the volume?
You can adjust the volume directly on your Bluetooth headphones if they have built-in volume controls. Otherwise, use the volume buttons on the transmitter.
Does this Bluetooth transmitter work with hearing aids?
No. This product is not compatible with hearing aids. It is designed for Bluetooth headphones, Bluetooth speakers, and Bluetooth receiver.
Can I connect two Bluetooth headphones at the same time?
Yes. The Bluetooth transmitter can connect to two Bluetooth headphones simultaneously, allowing two people to listen to the same TV audio.
Can I use a soundbar and Bluetooth headphones at the same time?
Yes. Use the bypass output and keep the input and output connection type the same: Optical input to Optical output, or AUX input to AUX output.
