Posted in the main suggestion thread a couple times, but no responses. Looking for something with a laid back sound, smooth top end, non fatiguing. If any frequency is forward, I'd prefer it to be the mids or a little extra midbass for a warm sound. Balanced is still fine though, as long as it's non fatiguing. I'd probably love the HD650, but since I don't have an amp or a powerful source I don't think that's a good idea unless my budget is at least 2x bigger. Recently been listening to a lot of Kpop/Cpop but I really listen to almost anything, including Metal, Classical, etc. The headphone being easy to drive is really important, otherwise I would just buy the HD650 and a decent amp. Not too sure where to start. Seems like the Momentum and Amperior aren't bad choices. I do love Sennheiser in general, but maybe the Momentum sound signature is a little preferable. Portability is not super important though - no preference on open, closed, etc. I owned the SR60i and HD25-II. Didn't like either a whole lot, but I liked the Grado less. This will probably be specifically for home use with my laptop, so a relatively cheap amp isn't out of the question if it's within the total budget. Thanks.
