Pero lo que más me gusto fue la batería, dura horas y horas. They keep the Apple iPhone earbuds in my ears. So theres no fixing that. Im wondering how long until the tiny wires inside it start to break. I mounted mine to my tonneau cover and supported them with steel underneath. I did some research and found that music studios use Sennheiser (never heard of them before) so I ordered the in ear Sennheiser which were okkkk but found that they worked better for me wearing them upside down and only then the ear buds didnt continuously fall out and the sound was better. They connect separately to the phone and work one at a time. Last night I brought them back in, but did not mention it to anyone and I was woken this morning to my whole family complaining that they smell the asparagus again. If you go to the specification, the sound quality is good but not worthy and mind you there is no bass so it totally depends upon your taste if you want at least little bit of bass in your music then dont buy this product.
