Ok, It's been a while since I've posted, and really, I'm just getting back into headphones. I'm working in a shared studio space and am in need of good cans, that are wireless. So, based on reviews, the Sennheiser RS 220's seem to fit the bill (back ordered I'm afraid). Anyway, I do know they are open and I'm concerned it will annoy my neighbor. It's an all-concrete space and VERY acoustic.
Short of making wooden domes (as I've seen before) is there anything I can do (besides lowering the volume) that will at-least lessen sound leakage? Can they be opened up easily to perhaps tape up the grill and/or fill the cavity with some sort of sound dampening material? I know this will change the sound, but any tips - one way or the other - will be much appreciated.
