Sure, you can add a 2nd pair of headphones to HT4186. 

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 -

  • Avanrtree NB16,
  • Avanrtree HS063,
  • Avantree ANC031,
  • Avantree ANC032

Troubleshooting: Why my second headphone does not have TV sound?

If your second headphone has connected to your cellphone before, now you connect the transmitter, then you will see connected, but no sound.  That is because the A2DP (Advanced Audio Distribution Profile) is occupied by cellphone. 


To solve it , please make sure cellphone Bluetooth is turn off when watch TV. 


If still fails, please clear pairing history of second NB16,  then pairs again with transmitter by using button B 

how to clear pairing history of NB16 
After turning on, press and hold both “+” and “-” for 10 seconds until the RED and BLUE LEDs are BOTH on for 2 seconds (looks PINK) - now all the paired history of the headphones is cleared. It then enters pairing mode automatically with the LED flashing alternately RED and BLUE.
