Uncomfortable, unsuitable for music listening.
Very uncomfortable (I have a big head), even with the glasses off. The headphones, loosened to the maximum, press on the top of the head, on the temples, crush and heat the ears. But the sound is also disappointing. I believed in a problem of driver bluetooth at the beginning, but tested on telephone, computer, bluetooth 4.1 or 5, update of the drivers, connection cable jack: the sound is always the same one. With the jack link, the headphones become passive and use the computer's amp. Classical music or metal, nothing is pleasant, except a bit of pop, but not just any pop. The highs are aggressive, while the mids are muffled, no spatiality. There is also a background noise audible in the periods of silence in bluetooth. I only held it for a maximum of half an hour before removing it with relief. Product made in China, microphone not tested.
