Sound isolated gaming

Budget around $300.

Primary desires… most minimal sound leakage, imaging and stage. I’m not a major fan of the Beyerdynamic clamp, pads and adjustment or I’d just call it with a pair of cheap 770s.** I’m also very open to IEMs but my only concern would be long term comfort but can’t confirm.

With this I’d be using my su8/a3 setup.

**I have a modded pair of 880s. With multiple hours of use each night the clamp becomes very lose, pads should last longer, and adjustment struggles to stay in place.
