Review on Soundcore by Anker Life A1 True Wireless Earbuds: Customized Sound, 35H Playtime, Wireless Charging, IPX7 Waterproof, Button Control by Peter Caw

These headphones are just great! If you want to test the bass, see Nigel Stanford's video entitled Cymatics. While I love these earbuds, the only downside I've found is the rubber piece that adjusts to the ear (various sizes available) seems to stretch over time and as a result the earbud doesn't fit as snugly like a few weeks ago. It would be nice if they could solve this little problem. Otherwise, they are very much worth the dollars invested. Plan to follow this brand in the future. The bass sound is amazing!
