The sound quality is top notch. You can find detailed information about its merits in the reviews of professionals. I don't like IEMs that go too far in the ear canal and it's a good balance of soundproofing and comfort and I can wear them all day. Bluetooth module connects well to my iPhone, good signal and battery life for its size. I wish it was USB-C and the port was in a more convenient spot, on the bottom rather than on the side where it's tucked under the clip. They're a hassle to charge compared to AirPods, but that's not a bother. The companion app is nice and offers some interesting equalizer options for those who aren't a purist but want premium quality.
