I care vocal, mid and high.
I am looking for a headphone which makes vocal deep in my ear.
+1 for HE-400. They can be had for closer to $330 if you look around too. I've been enjoying mine since they arrived several weeks ago. They respond well to EQ-ing and have some amazing bass, mids and hi's. Clear, detailed, the seperation must be heard to be believed...I can follow a single instrument through an entire song if I choose to! Well worth a serious look. I am a huge fan of planar magnetic headphones now! I can't afford anything better, but the HE-400's are the best headphone I've owned A friend of mine just got a pair of Q701's and loves them as well!
Honestly there are a lot of good options, spend some time and research all of the suggestions provided so far. Also where and how you plan to use them counts too.. portable use? Home use? PC use? Gaming too? Do you have something that can drive headphones (amp)?
