Very convenient, good sound, one-button connection, I wear them under the collar on a polo shirt and the microphone works perfectly. As for the negatives, I mention the average quality of materials and the fact that it has one button for all functions, so you need to know where to press, sometimes you press the wrong thing. But you can't have it all at this price, can you?

Amazing sound, tremendous battery, they hear you perfectly, unfortunately poor construction, the cables on the speaker board came off at the beginning and then the battery cables came off
