- The Bluetooth radio channel, which has a constrained bandwidth, and any codec are to blame for the sound quality and microphone issues, not the headphones, almost no one said. The music becomes perfectly clear as soon as you connect the headphones to the provided wire, and your speech is heard clearly and without delay in the microphone.
- They are always a tradeoff, as are all other wireless headphones in this class: Comfortable wireless operation, excellent sound quality with decreased volume, and a subpar microphone. Or the ideal voice and tone, but through a wire. These are headphone for indoor use. Their fragile skin and plastic will quickly lose their attractiveness if you walk with them every day on the street or in the subway, and even without moisture protection, if it rains, you run the risk of permanently burning their electrical contents.

A girl had both legs amputated by a tram in Strogino a few years ago; she was listening to music through headphones and had no idea the tram was coming.
