Got my 598 for x-mas. and I can see a little of a crack on the middle of the sennheiser name on the left ear cup.
Should I not worry about it? should I get my warranty?

That's unfortunate, as this was a common issue with HD 5x5 series. One would have thought that Sennheiser would have fixed this issue with the new HD 5x8 series, I quess not. Anyway, to answer your question- your headphones will be fine as long as the crack doesn't expand past the point that causes the actual cup to fall off. That process takes several months to years depending on how roughly you handle your 'phones. If not you can always contact Sennheiser to have your 'phones repaired.
My HD558 don't have this problem, but I've seen several HD598s that do. Too bad, really, that Senn didn't put more effort into fixing this issue. You can try inserting some clear nail polish/acrylic into the cracks or over them; I think I read that it helps somewhat.
About time Sennheiser up the build quality on their headphones, its not really acceptable.
yeah I know. one months of usage and I paid 200+ for these.
Even though looks and sound is amazinggg. the build quality is horrible.
The HD 650's are quite solid but the build quality of lower level Senns need to be improved. . . my HD 485's were cheap so it's not a big deal for me but they are cracked. I just taped it up.
My 555's cracked on both sides in about 6 months.
I glued them together to keep it from falling apart eventually.
I'm quite amazed Sennheiser didn't fix the problem as it's so obviously a big construction flaw. I've always babied them but still they crack.
this today, yesterday was a tiny little crack.. I guess im going to returns these and get the ultrasone 900.
Well, get the word out: the HD598 suffer from the same cracking problem as the HD5X5. The HD558 apparently do not.
Neither the HD 448 (similar construction). Well at least now i know for sure i won't spend the money on HD 598, though i liked the color. Will it be HD 558 or something else. 
I have had the same exact issue with my HD 598s. I picked them up when I was in Germany in December and a few weeks ago a crack began to form in the exact location as the posted picture. I left a message with Sennheiser a few weeks ago and did not get a response. I emailed them again this morning. I hope the 2 year warranty covers this issue. To bad, I am enjoying these cans so far.

let me know how thing goes out. so far it not getting any bigger which is good. if this little crack stays for another 3 months... by then ill have my ultrsone 900 and will be using the 598 for occasionally usage
Not really, the HD650's feel pretty fragile to me.
I'm sure the 558 has the exact same casing as the 598 just with a different color, so eventually those will break, too.
