FWIW, the quality on these arent that great.
The rubber surrounds of my lightly used (I use Jaybirds for workouts and sweaty activities) Soundsports (including the power button), started parting from the main body 2 weeks after the warranty ran out, the rubber gasket thing at the base of both earbuds slid off and the bluetooth connection started out great but within months, it struggles to connect to my Pixel 2.
GF's Soundsports, bought at the same time, has exactly the same problems.
