Hi all. I've owned my Grado SR80i headphones for a couple of years now, and I think it's time to change. My problems are lack of comfort, sound leakage, and lack of portability. Here's my other problem. I'm spoiled, and can't settle for any quality of sound less than the Grados. The only alternative I've considered so far is the Shure 215 in-ears, but I haven't tried them, and likely can't before purchase. All others seem to have this short comming or that short comming. I listen to, mainly, jazz. Some classical, some rock, but mainly jazz. Please help me! What do you recommend? And thanks.
