Shure SE535 (Metallic Bronze)

Pros: well balanced and detailed, clear sound
smaller in size; better fit than the predecessor (SE530)
detachable/replacable cable
good noise-cancelling

Cons: although they made improvement, it is not the most comfortable

Summary: I am a serious classical musician and I recommend this product without hesitation.
The sound is unbeatable. I contently use it to listen to symphonies, opera, solo and chamber music etc.
The noice-cancelling is also great. I can't stand the excessive noise from trains, airplane..
The cable is replacable which means you do not need to spend another $500 everytime it breaks.
It is not the most comfortable but it is definitely improved. Once you get used to it, it will not be an issue.
Trust me, I am INSANELY picky.
