Sometimes I wonder if the K701 is the end to my (admittedly short) audio journey, or if I can find something better. I LOVE the strengths of the K701 - the detail, the soundstage, the not-laid-back-but-not-overly-aggressive presentation, and the earpad comfort. However, I'm also keenly aware of the drawbacks - the lack of bass (especially when I switch from my X540s [which are not high quality by any means, but still... subwoofer]), and the discomfort omg omg omg. I'm only slightly bothered by the headband bumps after a few hours, but I had to ghettorig the adjustment system so that it could be large enough to fit my head. Sometimes I wonder, with the way I did it, if it's good for the headband... it certainly doesn't look nice.
Anyway, my primary concern is the comfort and presentation of the headphone. I've been looking into Audio-Technicas and Beyers, although I'm not completely sure if I'd get what I want. I really like AD700s, but there the bass is also lacking; I'm not sure if I'd like the Beyer mids, after being spoiled on Grado and AKG mids. As such, I've been extremely hesitant about where I should move next... I don't have enough liquid money to keep two headphones at the same time, so I know I'd have to get rid of the K701s if I found something I liked more. But I'd also feel dumb buying a pair of headphones, then selling them so quickly because I like ethe K701 more. Doh!
