Wow, I’m shocked to learn that they still make the HD200 Pro but discontinued the 451/61/71, that’s so stupid! That’s exactly backwards from what I would have guessed would happen. Thanks for pointing it out, I’m sure this will help others also.
It’s tough to match the 461 as far as its combo of decent sound signature, rock bottom price, and removable cable. You’ll probably have to step up to something in the $99 range, like the M40X or the Pioneer HRM-5. The Sennheiser HD559 is an upgrade in basically every way as well, if you don’t mind an open backed design.
I’m sorry I don’t have a better suggestion off the top of my head! Those 400-series Sennheisers kind of sat in their own little category. I guess they weren’t really selling, and Sennheiser can still get away with charging people more for the same thing with a permanently-attached cable. Ugh.
