microphone and hearing on call both fine. Hardware worked well. ich habe noch nie solsche tollen flipflops besessen! Love it 😍 so stylish 😍 very very happy with my purchase 😁 dont hesitate, buy it 😁😁😁😁 Nonetheless, it is best out there and if you own Iphone, I dont see a reason for not buying this. The sounds great - and if you get pair of foam tips - even better, but, be careful when trying different rubber tips included in the pack, they break very easily. Apparantly, it transmits sound just fine. I thought I had lost my original ones which are ones showing in the package. Leider ist die Beschreibung falsch. It worked good and charged pretty fast the first two weeks, and then it stopped working suddenly.
