I use this for Windows gaming, and it works very well.
I use it for Forza Horizon 4, an immersive racing game,
and it provides a very good experience. It connects
easily with the game, and it provides good physical
feedback. It offers excellent value for the money.

Excellent set of budget headphones. I use them with my
"new" Galaxy S22 phone. They provide good stereo sound, that is considerably better than that from the
speakers of the phone. They drain the battery of the
phone far less than the phone speakers, or than using
bluetooth headphones. They deliver very good value.
