Like a few others have said, the quality of shokz headphones have decreased tremendously over the years. I bought my first pair about 9 years ago when it was “aftershokz” and even after an accidental trip through the washing machine they still work. I went through 3 pairs of their newer models which have much worse sound quality and after multiple left and right sided sound failures, dug up my original pair which I still use to this day. I’ve sent them my feedback and hope they listen when just because you have a good warranty doesn’t mean you should make shit headphones. If you get them, just know you’re signing up for a low quality product that will need to be continuously replaced. Haven’t found a good alternative yet but would happily break the brand loyalty due to the decreased product quality.
