First, I want say that the sound quality is top Tier. I’ve had a few earphone, status between pro, Beats Pro x2, 1st and 2nd gen EarPods. I think I have some experience. To be totally fair to these, I’m a very heavy user (11+ hours a day continuously for 4 days per week) I’ve had a few different experiences with these, going anywhere from 5 hours - 8 hours per day. In 3 weeks I’ve only had 3 Bluetooth issues. Overall I give these a strong 7
