Came fast. Instruction print is so tiny I had to use penile&magnifier, they are limited on info but ez pairing, good sound. 2 probs: ear buds big, fallen 2x's outta ear, almost lost & charger info is 2 lines so u are on own. 2nd: charge on buds g@'ve Mayne 2.t/3 he listening & must recharge often. I think 4 price are good but I'd order 2 as of maybe losing bud(s) w/falling out. When works, its good

Works like any other Bluetooth device. Charge in case. Works with my iPhone. I’d prob buy it a 2nd time if needed.

So far, they have performed well and the sound is better than expected.
