I like it.

Why are you replacing the cup? Why not just replace the drivers? Then the HD600 housings will match completely (marbled). Its really easy to remove the drivers, just wedge a small flat blade screwdriver in there and pop it out.

I live in tucson.

What model are those boston acoustic speakers? If they are the Media Theater series, with the 8 inch sub, then they are the best 2.1 system I have ever heard for a computer... The bass response is amazing for that system.

In my opinion the best method is the spoon method. Slide a spoon in the area between the 2 housings and use the taper to spread the halves apart... You could try fixing it by slight sucking on the driver on the cloth side. Keep trying it until you fix the problem.

Putting 5xx/6xx drivers in grado housings could be done, but it would be harder... You would have to sand down that little wire channel on the senn drivers, and be VERY careful with the wires... I also don't know what you would do for a cable solution, those tiny wires would have to remain...

The spare driver was from an sr-60 that I accidently killed. I would be the first to do this, but it would involve killing some cans . I have working ms-1s and (now) working HD-600s. If anyone has any dead HD580/590/595/600/650s, let me know. Id need some grado/alessandro drivers as well. It...

Well, for the time being it appears to be fixed. I took some masking tape and gently pulled the driver up. Everything looked good. I played music, bass rattle was still there but not as bad. I gently sucked on the back of the driver, heard a pop, now all is well. I think what happened was that...

While looking at my blown right HD600 driver, I found that the SR-60 driver fits perfectly into the hole... This could lead to some interesting hybrids.

Do these drivers look good? I found something rather interesting while they were out. SR-60 drivers fit perfectly into the hole for the senn driver... Followup in the DIY section.

There was a small piece of the wire that looked like transducer wire about 1 inch long sticking out the hole... It brushed off, it didnt appear to be attached to anything. As you can see, the driver looks fine...

Right side driver is definitely blown, when I popped the pad off there appeared to be some of the wire thats used in the transducer... Will post pics soon. Anyone know about sennheisers rma process

Big big problem... tried playing A Perfect Circle's "The Noose"... It sounds like the right driver is blown. On any kind of bass impact there is a horrible distortion... Any suggestions?

Just got my refurbed HD600s from amazon... Some first impresions are: Man, these are sharp looking. Put them on my head... Hmm they clasp kind of tightly (vice). Wait, these are supposed to be more comfortable than my MS-1s? They aren't - to me. Plug them into the amp im using... The noise...

Yea I have, it is a problem with the phones... Its not severe, it just seems like the right side is tiny bit quieter. I have put like 1000 hours on these since I got them, though
