First of all I must preface that if you purely want these for sound quality they are excellent for the price, the only issue with the audio quality that I noticed was a slight hissing in the left ear. The main problem I have with this product is the charging case, the most obvious thing is that the case is massive, big enough that you could have issues with fitting it in pockets and even then it’s too big to feel comfortable. The second issue I have with the case is the charging indicator leds they are very bright for their size enough so that having the case in a dark room was actively disturbing my sleep, this is made worse by the fact that the indicators do not turn off until the buds are fully charged and if you are charging the case they will never turn off. The size of the case is something that was done for comparability’s sake but the lights are just ridiculous I have included photos comparing the case to that of the AirPod pro gen 1s in order to highlight its relative size
