I had two pairs of bose frames when tgey came out and they are (theoretically) fantastic. They sound really good, and you don’t have anything in your ears. Shokz are nice, but i hate when they were lound enough that you could feel them vibrate. Anyway, bose frames, too expensive, because both of them broke the same way, tgey are just too fiddly, and the little contact in the hinges broke i think. And no one ever made knockoffs and even bose gave up
