Unfortunately, I found them very uncomfortable for my ears. Even while not laying down just wearing them while working they are painful after a few minutes as their core is large and hurts my inner ear. Also surprisingly they were un pairing unexpectedly causing blaring sound from my phone into the bedroom during the night awaking me up. Maybe to do with my settings but still they are not intuitive to set up as much as you would expect from this brand.

It’s not very comfortable.

Best purchase ever. I've never slept so well as I am with these earphones. They are my savior, and I would definitely recommend them to everyone.

I started using these with the model A10. They lasted most of the night and were just the best. I lost them. Then I bought the A20. The right earbud's battery died in about 3 hours and has gotten really bad. So, I bought these A30's. Not gonna lie, they're awesome. They really do help. They block out sound and pipe in rain and wind. I sleep so, so much better now. The app sucks. It tries to force you to Bluetooth to an app. You can go to source and put local and it will just play rain sounds or whatever you want. The batteries last longer too!

Works outstanding has improved my sleeping with the use of ANC feature. Extremely comfortable.
