Good sound especially bass, feel every beat. The microphone, according to the interlocutor, is good, but I heard better. The noise isolation and transparency modes (switched in the mi buds m8 application or by long pressing) work well, without any complaints, except that in the transparency mode noise is heard from the headphones themselves. The plastic is good, strong, nothing staggers. Both the case and the headphones are charged quickly, they work 4-5 hours with the case 20+ hours if used actively. The volume margin is good above 70%, the sound did not have to be added even in noisy places. In general, I recommend.
