Everything is fine, I liked the product, I bought it for a reason.
What I really liked, the build quality is very good, I thought the volume control on the left ear would not be convenient, but it turned out to be exactly what you need.

Pros
Good sound, work especially well with their USB card, soft bass, easy to recognize where the action is in games, good headphone materials.
Cons
They probably worked for about 2-3 months, as a result, the very usb card that gave a juicy sound refused, the headphones themselves had no problems, but without the card the sound became flat, I wrote in support, I'm waiting for an answer .
