I have been using it for more than 1.5 years, so far there are no special complaints. The sound seems very good to me personally, there is a setting through a proprietary application. There was a jamb with the left earpiece: it was discharged to zero and went into sleep mode, i. E. did not react to anything, including charging. I solved the problem with a kind of "resuscitation", on YouTube there are guides for solving this problem. I was frightened notably, but, fortunately, in vain. When running, they hold like family, they never fell out. It was great in the rain too. The charge is kept for a long time, respect for this, the case allows you not to put it on charge for a long time. I really liked the noise cancellation, everything is cool. Well, the appearance, just a feast for the eyes, I took the red color and not a bit disappointed. In general, in 2022 I advise you to take a newer model, after all, already an outdated version, according to "experts". However, I am not going to change mine, so far they are 200% satisfied
