Review on KZ Aptx Bluetooth Module Plus Wireless Upgrade Detachable Cord (B Pin) with Waterproof Feature by Ana Ramos

Use with my KZ ZST10 pro. I should have known better when I saw another reviewer comment that the sound is constantly muted when your phone is in your pocket. I thought maybe that would be the problem so I took it off and no change. I thought maybe it was a song so I plugged in my headphones and there was nothing wrong with the song. This is incredibly unacceptable! Too bad there are no other options. I guess I'll have to get new headphones or stick with my $20 Walmart Jlab headphones that never turn off and have no sound comparison, but at least they work properly.
