Review on Bluetooth Headphones Earpieces Sweatproof Cancelling by Katie Smith

base. No complaints about that. However, the volume controls are touch-sensitive, meaning you have to tap to operate the volume slider. So far I've only been able to adjust the volume via the headphones once. This is a lesson in disappointment. It is best to control the volume via the device. The second problem is minor. I don't think the headphone case will charge the headphones unless they are plugged into a power source. The case is designed to charge the headphones when not connected to a power source until the case runs out of power. I will do more testing and update later.
