I would certainly purchase this item again based on the quality of the product and the service. The microphone is clear and Ive actually been complimented on how it sounds (trust me its not my voice getting the compliments). Not as good as over the ear headphones but enough that I have remove one side if someone is talking to me, even without music on. No fading this far, easy to string. One side of the headphone works sometimes, sometimes both and most times the sound stopped coming from both sides. Las pantuflas mantienen mis pies a buena temperatura y son supercómodas. Other than that, my microphone was in tact and everything seems to be functioning well so far, so I cant complain too much. Fit like a charm. If you have shorter toes at all, I wouldn?t get these. Really great sandals!
