Review on Pioneer Wireless Headphones Black SE QL7BT by Kenta Omura

I'll start with the fact that the declared 4Hz is not felt in any way (there is something to compare with). And I took it just with the expectation of this parameter. The battery is lousy. Periodically, it is impossible to listen to music at all - they "stutter" so that nothing is heard. Especially if you go near power lines. It's a total nightmare. You can safely turn it off. The wires are thin, and obviously quickly become unusable. In short, the purchase is very dubious. Money sorry.
