Love them. I'm working from home like so many others now, and I really enjoy the ANC feature. U like some other reviews, I've not had any real issues with it.
At times during video conferencing I have noticed some limited clipping and other unsatisfactory noises, but this is usually tied to the way the person speaking is using their microphone or audio settings on the device I'm using occasionally auto adjusting to max volume.
I use these primarily for video conferencing and the ANC function while at work, and I've developed the habit of popping them in the charger a few times a day now. They don't need the charge all that frequently, but initially I was only putting them on the charger after I wrapped up my day and noticed that around hour 5 or 6 they'd die on me if I wasn't trading which one was in the charger. Now I just pop them in the charge case after a long call and they're ready whenever I need them.
To test them out a bit, I did listen to some music with them, and I really enjoyed the audio quality in that capacity as well. I'm not an "audiophile", but I do appreciate a full, deep sound in the music, not the tinny "flat" sound you can get out of cheaper speakers and headsets. I listened to some Daft Punk and Galantis through these, and it sounded great to me. I like the idea of the app and the customization you can put into the EQ on your audio, but I've not really messed with it much. I primarily use Shuttle music player for any of my music which also has built in EQ adjustment, and as I mentioned earlier, I'm mostly using these for video conferencing.
I have not used ANC devices before, so there may be better units out there, but I have really enjoyed the ability to pop them in and minimise the overall sound clutter that goes on in an occupied house when I need to focus on work.
I also liked that there is a wide range of ear cushions allowing you to get really granular with ensuring the right fit. I found the best results from mismatching two different sizes.
I've been buying Anker products for a long time, and like mostong time customers of theirs, I'll say the quality does not disappoint.
