Okay, I don't know what's going on. I started out with the Senn Momentum (over ear) around Christmas time for a light, portable, slightly warmish set of cans. Sounded good demoing and got it home, enjoyed it but quickly lost its charm. Then, I finally got a chance to demo the HP50s and really loved the sound signature. Out go the Mos and in come the HP50s.
Took a while for the HP50s to arrive and have been spending that time listening to a lot of open cans (T90, X1). HP50s finally arrive and they sound so veiled, compressed. So, I burn them in for a few days and they do open up a bit...
But not enough. Now, I might have spoiled myself with all those open cans, but even my M100s sound more airy and open. I'd hate to chalk it up to a bad pair and wait for another pair.
Meanwhile, I'm really just looking for a pair to travel with and am really contemplating just exchanging these for a pair of P5s. Is that blasphemy? The clamping force on these aren't the best either, not to mention the look. I also thought about the Mad Dogs, but it seems I'd be spending quite a bit more and it'd also be a blind buy (deaf buy?).
Anybody prefer the P5s over the HP50s? Any others I should consider?
If your HP50s sound veiled, I'd probably ship them back/exchange them. My M-100s definitely don't sound more open than my HP50s (even with the XL pads). They certainly - certainly - don't sound veiled, but detailed and even a tiny bit bright.
Sound wise, I didn't like the P5's myself (the P7's, however, are pretty nice). If you're willing to consider on-ear headphones, you might want to give the Sennheiser Amperiors a try. Probably the most detailed, aggressive portable can I've heard.
If you're looking at the Mad Dogs, you might want to look at LFF's Paradox as well.
