works fine
It’s a good earmuff. it’s not that loud but you can listen to your musics without any interruption. The system of sound is good I can hear any steps at my house. I recommend it.
This Bluetooth adapter works great with my phone and fits perfectly on the side of the headset. The headset still fits in it’s factory case with the Bluetooth adapter attached. Best price and Quality product, can’t go wrong!
