I bought this model specifically as a headset for a PC, since I needed in-ear headphones, preferably with an external microphone (not wired like headsets), this type of headphones is quite rare and there are very few models on the market. There are no special claims to the headphones themselves. The sound is average. The soundproofing of the rubber bands is poor, however, this was not the most important thing for me. This external microphone, either it has a bad contact, or it is defective itself, sooooo much fonit. At the same time, if you turn it off, then the microphone built into the wire works better, and much more, but as soon as you connect an external microphone, a wild background immediately appears. As a sound card, I use a mixer from Yamaha and no other headphones with a microphone (and I have several of them) do not sound like that when connected to the microphone jack. Grade 2.
