I myself own an ATH M50 and found that the sound quality is nice and balanced. However, i can't stand wearing them for longer than an hour. I don't know but i think they are not meant to wear for daily usage? I felt that the headbands are too tight and the earcups are pressing my ear too tightly and plus the wires are tok bulky. I do wear glasses and that might be the problem, since the earcups are also pressing against my glasses hence hurting the side of my ear.
So, after trying my friend's qc15, the first thing i find is that it is super comfortable. It felt as if im not even wearing one. This feeling maybe make up for the below-par sound quality. Im not an audiophile and therrefore couldn't distinguish all the different elements in the music, therefore i consider bose to be good enough for my ears. Of course, i can tell that my m50 is superior to bose, but wearingthem for hours of travelling? U dont think i can stand that.
I'm stuck with bose qc15 or ae2 or any other comfortable headphones. I dont know whether qc15 is better than ae2, but the $150 difference between the two is a huge factor to me. Bose is very much overpriced at their pricerange, but im willing to get used headphones if nothing can compare to both the noise cancellation and excellent comfort level by bose headphones.
Any advice is appreciated and im willing to try new headphones that might suit my needs. Also if you can refer me to a place in los angeles where i can audition theese headphones, that would be great.
