I just wanted to share my opinion about these 5 headphones - all around 75-150 bucks except for the beats. I personally own or tried out all of them and I have to say by far the best bass headphones out of all of them are the Vmoda crossfade lps. The bass is crisp and undistorted unlike what I get when I turn up the bass eq on all the others - even the dt770. I just got my dt770 and I don't know if there is a burn in time but so far they don't have as much bass as the lmodas. I'm also listening to these headphones through a fiio e7. Not only are the Vmodas better in bass but they leak the lowest amount of sound (even compared to dt770 and hd 280 pro which people on here say have the least) and I believe are the most stylish out of all the headphones. BUT THE BIGGEST PROBLEM with Vmodas is that they hurt your ears like hell - when I first bought them I was so pissed at how little the cups are on this thing, but after a half a year of stretching they are getting more comfortable. Right now these headphones are only 75 bucks on amazon - http://www.amazon.com/Crossfade-Over-Ear-Noise-Isolating-Headphone-Gunmetal/dp/B003BYRGKY/ref=sr_1_7?ie=UTF8&qid=1353955395&sr=8-7&keywords=v-moda - I don't think you can find a better bang for buck pair of headphones especially if you have small ears.
