Just curious if anybody has opened up their HD-650s, and if so, how difficult is it?  Are there any instructions anywhere for doing this?

Thanks,

Jim

HD-600's aren't too hard to pop open, so I'd assume the HD-600 isn't so bad.  What are you needing to replace?  There are some photo walkthroughs here and there on the net.

Paul,

Well, the photo walk-throughs don't do me too muchgood :-).

Just toying with the idea of captive wiring at some point when I find the right cable recipe I like.

But I will probably get a pair of 600s too before I commit to that.

Hi Jim,
I just ordered a pair of the HD 650's. Am curious what if any conclusions you've come to regarding the cable? I've also ordered a Crack/Speedball amp and am anxious to experience the set up.
regards, John

John,

I actually ended up swapping the 650s for a pair of 600s, so I can't offer any advice on the cables.

I did just recently get a headroom/cardas "Fat Pipe" cable that I'm reterminating with a Neutrik right angle connector for use with the Crack and S.e.x. amps.

Perfect, this is just what I'm looking for. As a previous owner of both the 650 and 600 on the crack and SEX, what were your impressions?

Sorry, neither the crack or s.e.x is done yet, so I can't tell you how they differ or how the 600s sound.

I've only used them both with a small portable amp, which I no longer own, and to my ears the 600s are more open and transparent without the overpowering bass of the 650s.          I like them both but so far prefer the 600s.  That said, you really should do your own comparison as our listening tastes may be very different.

I too enjoy the HD600 over the 650, and the Crack drives this headphone superbly. All you need is a quality source and you are set. I also bought the bottle headphone cable which is just a right angle terminated cardas cable. Did not head a big sound change but it certainly looks nice and works well with the amp.

Hey Jim,

I bought a 20' Blue Dragon from Drew at Moon Audio, for my HD-600s.  It uses moulded Sennheiser connectors at the earpieces, just like the cruddy, veiled stock cable :-)

I've got about 50 hours on the Blue Dragon, and it's super clean.  It was a bit bright at first, settled right down in a few days.  Sounds very open, more forward than the stock cable without that darned treble "edge" that I always heard on the stock cable, and blamed on my ears/equipment/age/own stupidity...

I'm enjoying it immensely, and I've given up on trying to solder those damned little Cardas connectors once and for all... <g>

YMMV,

-Don
