The headphones are excellent quality. Sturdy construction and a nice finish on the case. Incredible battery life for listening with ANC off. Easily 12 hours. With ANC on, expect around 8 hours. The sound is quite high quality, with very powerful bass. They don’t distort at high volume and, generally, won’t disappoint when listening to songs, especially those with strong percussion. During calls, I was asked to speak louder than normal only a few times. The ANC is good, but not better than the OnePlus Buds 3 I had, which these replaced. Unfortunately, there’s no automatic detection of whether you’re wearing them, to pause playback automatically. To raise or lower the volume, both earbuds have to be worn at the same time, and you adjust the sound by clicking the left or right earbud... Not convenient at all. There’s no slider on each earbud for independently adjusting the volume on each one. The case really does work as a power bank. It could come in handy in an emergency. Don’t expect fast-charging protocols. Just regular charging. It also works as a stand for placing your phone in landscape mode to watch a movie or video. It also has a built-in cable for charging devices. I haven’t plugged a charger into it to charge the case. For me, though, since I use them every day, one at a time rather than as a pair, for listening on YouTube, watching Netflix, etc., the case lasts at least 3 weeks before it needs charging. I hope this was helpful. I’ve had them for about two months.
