Best sounding earbuds, even headphones I have listened to, left earpiece stopped working, hit it to check and it works long time, but I am hoping 1More releases the update, am sure lowering output mlW to restart the left and applying to HearID left restart is gonna save the whole manufacturing trouble, call quality both ways is perfect, sound is 8.5-9 out of 10, not for IPhone, Apple sounds similar with it's SBS @ 382 kbps, this product will not sound better than AirPods, will be louder for sure, this product is for non-iOS devices due to hardware requirements not currently met by any iPhone ever released
