Its true these feel like a glove for your foot! Teen son was happy with them. Its one of the reasons I chose this over the Hyper X Predator series. Se desconectan a cada rato I hesitated ordering when some of the past reviews said the shoe was huge. This was a total waste of money. (It?s meant for connecting with the earphone jack to the phone). I like the Brio Sol as they are very comfortable. After only a couple minutes of testing its clear that the replacement pair has the same issue as the originals. Just an overly expensive gift i bought for myself is all.
