Looked promising, but the blue pair stopped working after 5 minutes for no reason and on the pink pair the whole head of one of the earbuds literally fell off before I had a chance to use them! Despite taking SUCH a hit, my phone screen was flawless, not even a scratch! Overall have no complaints i just might have to get one for my boo now! They also last for hours. Stunning! It will fit almost any headset. I cant even use it with my phone case on my phone so its useless to me. Jedoch löst sich an beiden Schuhen die Verklebung der Lasche. Id rather have the wide width follow through to the heel. I think this trimmer is a good add on to my work out routine.
