The best thing about these phones is the Bluetooth stays solidly connected to my Apple Watch. Unlike some other earbuds I’ve tried, these don’t skip at all. I’ve had no issues with the battery life... I’ve never had them run out while I’m using them. Sound quality... not great. The bass response is poor. It’s slightly better if you can keep the buds firmly inserted in your ear canal, but they seem to work their way out of the ear. They don’t fall off, but they back out. I think this is partially due to the small rubber tab that helps retain them to the outer ear. It’s angled slightly inward (toward the head), and this may put a tiny bit of pressure that gradually pulls the buds out as that rubber tab straightens itself.
Solid Bluetooth Connection to Apple Watch, mediocre sound.
