NOTE: Since the Oasis Plus doesn't support aptX HD while dual link, we suggest you switch to "LL" mode for a more stable connection when linking with 2 headphones.
Step 1： Turn off the AS9S headphone.
Step 2: Enter the transmitter into PAIRING MODE manually – press and hold for 2 seconds, “TX” LED will start flashing GREEN and WHITE alternately.
Step 3: Place your 2nd set of headphones into Bluetooth PAIRING MODE (Please refer to your 2nd headphone’s user manual).
Step 4: Keep the devices close to each other and wait. Once connected. You will hear voice prompt “Connected. Ready for use.” Turn on the first headphones and wait for a few seconds. Once succeeded, you will find LEDs A and B to both be lit.
Next time, just turn on both headphones and they will automatically reconnect to the transmitter.
