I have got some KRK KNS 8400..they are a closed cup and offer, according to the book, up to 30db worth of noise reduction from the cup alone, not wireless but the lead does pull out of the phones...if you tread on it or just to swap lead type from curly/straight, it has a seperate piece of lead with a slider switch for volume aswell. Plastic type shells with a sturdy metal strap/slider..I think these came in at just over a one'er tho, apart from some sennhiesser's back in the day, I have managed with Sony £20 specials for years, I think I prefer a closed cup...and then I can just lift it away from my ear if I need a bit of background in there...ythe semi open Sennhiessres bled too much background thru all the time for me...but as uz a scratchpert is that what u want?
