I'm fascinated by SE7 circle powder. Is it worth buying? Let's talk about used ones

I used the black SE7 for nearly 3 months, and I was completely satisfied. I mainly wanted to find a noise-free game, so I chose it. The sound quality is excellent and there is no noise at all. This model is upgraded on the original basis, and the earmuffs can be turned left and right or folded up and down, which is particularly convenient to carry.
