So my HD205s needed new earpads. Can't sell these for more than $10 and I wasn't about ready to send a letter to Germany to request those crappy pleather earpads of pain. I wanted velour and I wanted to MOD! I heard a lot of people put DT 250 pads on their MDR-V6s to improve comfort and keep a nice seal. And I figured, heck I'll try and see if they'll fit and if I can be arsed to make em fit... if not I'll give the earpads to my mum who has V6s. So they didn't... but the adapter plates that came with the pads inspired me. They were similar in feel and strength as those black DVD cases, so i figured, heck, I'll just get one of those old AOL cases and cut me out an adapter plate. Gotta love AOL. Enough backstory... Materials: Sennheiser HD205 Beyerdynamic DT250 Replacement Earpads (w/ plastic adapters) Black DVD Case (ABS plastic) Scissors Dremel or similar tool Xacto Knife Masking Tape (preferably a color you like, I used blue painters) Pen, Pencil or Sharpie This mod is reversible So I used the plastic adapter plate from the DT250 to draw an outline on the DVD case then cut out the piece i was gonna work with. Then I used a dremel with wood grinding bit to clean out a hole in the middle. (I also used a file to wittle it down a bit, not necessary though). After this you want to wash it off. get all those little scraps of the edges and make it clean Next, line it up with the HD205's own adapter plate and make sure none of the holes are covered. At first, I tried to use glue and various adhesives. Nothing worked. regular glue created gaps and ugly blobs. high strength adhesives just ate away at the plastics. In the end, masking tape was a better solution and it's a bonus that it's reversible. if you can avoid taping over the holes you don't need an XACTO knife, though it helps to get very precise cuts when getting the tape of. After that, just put the new dt250 earpad on as you would put it on the original adapter plate. I didn't put the foam in at first, but I did later. Then the new assembly should just snap in into the HD205s. ENDRESULT IN ALL ITS CRAZYNESS!!!!!! So in the end... Comfort is improved greatly, the phones look a little snazzier (blue is siiiick), SQ is a little better (everything is a little better, a lot less muddy), isolation is VASTLY improved. I think this would be great for DJ's on a budget. eBay price of 205s are at $11, pads at $18 and factor another $1 for materials and $30 gets you a decent set of comfy and super isolating phones. Not to mention, this is reversible so you don't have to sacrifice the DT250 pads, just take em off if you don't like the mod. Make a new adapter for another set of cans .
