Love These More Than My Husband

They also switch to softly pattering rain sounds once my book is silenced, as if I'm a crib-bound toddler and my momma snuck in and knew I needed just a hint of ambient noise! No joke, I'm getting better quality sleep according to my Apple Watch. There are no buttons on them to accidentally press and blast yourself awake. You control them by aggressively tapping them. You know, like you'd do anyway if someone woke you and you had to tap play to get your soothing sounds back. Battery life is astonishing. The case is slim. Via the app, they connect to two devices. Sound is as good as any other Soundcore product I own, and that's beyond excellent. Buy them. Buy them now. The tiniest life-altering purchase you'll ever make!

I love these earbuds.. I sleep so much better with them on especially when I have annoying company. Plus they are lightweight and at times, I forget that I have them on!! I highly recommend these for light sleepers who seek peaceful sleep in an unpeaceful environment.
