The headphones are good, after them I can’t pick up others for myself. I thought to listen to plugs and earbuds, but absolutely not the sound. Now I want to buy another one like it, and maybe even the same. In mine, the right speaker stopped sounding, judging by the reviews, a fairly common phenomenon in this model. Although for the last six months I have begun to carry them with me very often, and I think that the main reason is that I folded and unfolded them endlessly. I recommend for purchase, if you use them permanently, I think there will be no problems.
