The earphones dont fall out easily on the ear, even if I dont shake my head, it seems that my choice is correct, each of them can work alone and connect to different devices. That’s alright though because he’ll grow into them, plus he still walks just fine with his shoes being a little too big! El único inconveniente que encuentro, es la posición del micrófono. The cord is really stiff, which makes it somewhat uncomfortable to wear (it doesnt hang easily), maybe that will relax over time. Sometimes the left and right are at different volumes and randomly alternate which ones louder until I disconnect and reconnect. Se usó máximo una hora y se rompió el cierre, inservible. I got 32 pairs of shoes and 4 pairs of boots on it. If, down the road, the sole comes unglued, as others have said, Ill update my review. I pity whoever inherits the title of daughter in law. They say they have a hard some and can be worn outside.
