Daaah I just bought both. I read about 30 pages of this thread and kept going back and forth between the Tts and the Philips. I ended up getting both because it seemed that the Thermaltake had slightly "more fun" and more refined sound than the Philips but the Philips sounded more neutral and balanced and could be worn over-ear for the gym.
Funny. The last thing I bought from Thermaltake was an AM CPU cooler for my rig. Headphones seems like quite a stretch in terms of diversifying.
You make well buying both, because their signatures are totally opposite ... TT are cold, more analytical and poor isolated, SHE warmth and bass, with good isolation, better for the gym.
I like both equally, depending on music genre.
