Does anyone have experience to how these would stack up against the Sony MDR-Z1R?

How do these match up with the HD 800S? I'm looking at these and the Sennheiser HDV 820.

I purchased the Sennheiser HD 800S some time ago and while I enjoy them very much, I do miss the warmth of my Z7s at times. So, if there's anyone here that owns both the Z7 and Z1R how much of an improvement of sound quality could I expect? I'd hate to blow $2k just to find out that the Z7s...

I purchased my pair about two months ago, and I don't have the rattle problem. I could just be lucky of course.

1) Philips Fidelio X1 2) Sennheiser HD 598 3) Beyerdynamic T-50p 4) Sony MDR-1R

Hmm, it appears that the Philips Funai deal has hit the cliffs.

    Not a wonderful shot, but here's my Philips Fidelio X1 on them. I think they look quite good with larger headphones. 

I just purchased a pair of these, it's still early to tell but I think my Beyerdynamic T-50p sounds a bit better, but the MDR-1r is so ridiculously comfortable, and they look amazing. Definitely a pair of headphones I'd be proud to wear outside.

I'm thinking about buying these to replace my Beyerdynamic T-50p as my 'on the go' headphones. I still can't decide if I want the silver or black version.

It's such a shame there are no replacable pads, especially since they're such dust magnets.  If I clean the pads, it's going to be littered with dust the following day again.

Sennheiser HD 598

I'd never wear these headphones outside for all the reasons you mentioned, but they're also incredibly large and would attract a lot of attention. The stock cable is also far too long. Other than that, I do think the X1 isolates a -lot- more than my HD 598, I can barely hear my surroundings on...

Here's mine ^^ Been using them with my AudioEngine D1, quite happy with it, but I wonder if there's a better amp to pair these with.

How are you enjoying the D1 so far? IME it gave the HD 598 a more pronounced bass, but somehow I felt like the soundstage did become a bit more narrow. It was quite a significant upgrade from my Xonar DG, it made the sound more 'alive'. The D1 also seems to pair very well with my Fidelio X1.
