HT4189 - Troubleshooting - Volume control does not work



1. Headphone volume button ONLY works when the headphone works under Bluetooth mode. If you use the headphone under wired mode, the volume buttons will NOT work. 

If you use HT4189 as a set, or use the headphone with your cellphone / PC as Bluetooth headphones, you can tap the volume button and adjust the volume. 

2: Make sure you TAP the  "+" "-" but NOT press and hold it. Make sure you tap the "+""-" on two ends NOT the MFB button_____20180926134738.png in the middle.

3: Hold the headphone in hands, buttons horizontal, then quick click the volume buttons 10-15 times and see whether it works.  

If still no luck, please contact
