I am most concerned about comfort and sound quality. Which of these is the best in these categories? Also do the AE2's provide good isolation?

At first I thought they were closed but after reading some reviews I found that a lot of people say they leak sound. Could someone please help me figure this out?

I am wondering what the most comfortable headphones under $300 are. I currently own studios and would like something more comfortable than them. Preferably leather or pleather ear cups and they must be around/over ear. Thanks!

Which of these are the most comfortable headphones?

Are they worth the $300? I am looking for very comfortable noise cancelling headphones with preferably leather ear cups. Thanks!

Are these good enough headphones that spend $200-$250 on? I need headphones with great comfort (around ear) so that they could be worn for 5+ hours without breaks. They also have to be very good at noise cancelling. I found a pair of these on eBay for $198 and a pair on amazon for $240. Please...

What is the best store to try out and buy headphones? I live in Southeastern Pennsylvania if that helps. Thanks!

Are these headphones better than beats studios? I currently own studios and am wondering if these are a better improvement. I am interested in comfort and sound quality. Please tell me all you know about these headphones. Thanks!

Should I buy the audio technicas off eBay new for $200 or save up my money and get the bose for $300. I am most interested in comfort, noise cancellation, and sound quality. Durability and build quality are also important. I enjoy a tight bass along with crisp highs. Also I am not an audiophile...
