Anyway, both pairs are comfortable enough to wear, but while one pair is sensational, the other is just ok. She said she has to push other types of headphones to her ears to hear well. Made as cheaply as possible. For me, they dont isolate very well. Just as good as the branded pair. But otherwise, it works and doesnt offend me. * 30 minutos: 59 % de batería. So theyre great in that aspect, but my biggest problem is when Im using them and the bluetooth seems to disconnect or cut out which is pretty damn annoying.
