I've had these Sennheiser HD-200 for ages now and have always found them to be an extremely honky sounding pair of headphones, so much so I have only been using these as test 'phones for amps I have modded (ie: 'phones I don't mind blowing up!) if they play music I transfer over to my HD-600 for a more in-depth listen.
I decided to have a look at these under the bonnet and the first thing I noticed was the enclosure was so thin and resonant compared with the much thicker, denser enclosures of the HD-25. This got me thinking......... if I were to add a dense material to the enclosures would it improve the SQ? In a word YES!!
I got hold of some of this stuff and went about applying it to the HD-200 enclosure. It is extremely adherent stuff and very easy to work with, a bit like plasticine but a thousand times more tacky (it will literally stick onto water!) it is also very dense and acoustically "dead".
First off I popped the enclosures in two, you will need a small screwdriver to gently push the white retaining clips to one side whilst pulling to seperate the housing.... once seperated here is the part you damp with the butyl tape:
Roll it in your fingers until it becomes tacky and form it into the enclosure as shown:
Put the 'phones back together and seriously be prepared to be amazed! TOTALLY different sounding headphones! The honkiness has disappeared, the bass makes your toes curl and these are now as close to the HD-25 as you're likely to get. An absolutely incredible transformation, it's amazing what a bit of butyl tape can do!!! I may very well try this in the ATH W-1000 once they have fully bedded in.
