Thanks for the feedback. Recently, I listened to a bunch of headphones over five hours.
- Sennheiser HD6 Mix. My biggest deception. The most comfortable of the headphones I tried, but the sound was plain weird.
- Shure SHR1540. Good stuff. Maybe the most euphonic of the headphones I tried, but not the most neutral -- the sound is warm and somewhat soft.
- NAD Viso HP50. Ugly, but sounds good! I liked it as much or better than the SHR1540, and it is more neutral. The sound is very cohesive.
- Sony MDR7510. The biggest surprise. I tried it mostly to see if the MDR7520 would fit me, but the sound was actually quite good. On par with the HP50, IMO.
- Sennheiser Momentum. Best looking, with good neutralish sound. I liked the HP50 just a bit better, sound-wise.
- Sennheiser Momentum On Ear. Very cute. Same sound signature as the Momentum, just not quite as refined.
- Audio Technica M50x. Not bad. While it isn't quite a basshead pair of headphones, it is still clear that the bass is north of neutral.
- Sennheiser HD25 Aluminum. This is a basshead pair of headphones! The sound is good, but clearly not neutral.
- Marshall Monitor. Weird sound, if not quite as much as that of the HD6 Mix. Muffled. Its sound can be changed, though, and I didn't try that.
And, according to Sony and some comparisons I've read, the 7510 is similar to the 7520 but the later is just better in every way. It should be too, considering the price difference. No doubt the 7510 is better value for money, but I'm not sure how much you're taking that aspect into consideration?
