Review on Sony MDREX15LP/P In-Ear Headphone (Pink) by Wei-Yin Chang ᠌

Bought 4 pairs of headphones. In 2 of them, one of the headphones began to work much quieter after a couple of months of use. I already thought to change to go, because. service life 5 years. It turned out that this was not a marriage, but a marketing (?) trick. Removed the filters, the sound returned back. (on the picture) The guarantee, of course, disappeared after such frauds, but, most importantly, they work. If it wasn't for this problem, I would have given it a higher rating.
