Step 1: Place your 2nd set of headphones into Bluetooth PAIRING MODE (Most time is LED flashing BLUE and RED).
Step 2: Enter the transmitter into PAIRING MODE manually - press and hold B for 2 seconds, close to B flashes BLUE and RED alternately.
Step 3: Keep the devices close to each other and wait. Once connected, close to B on the transmitter will turn SOLID BLUE.
Reconnect - Next time, pls turn on transmitter and A and wait for A to work first (both transmitter and A are solid blue). Then turn on B and click the main button on the second headphone once and wait for it to reconnect to the transmitter. Now both headphones should work.
To achieve no audio lag effect, your 2nd pair of headphones MUST also support FastStream codec with less than 40ms latency, otherwise BOTH headphones will work using SBC codec with about 200ms latency.
For headphones support FastStream codec, you may consider one of the following -
