So I've been on a quest to find the "best" budget headphone for listening to music at work and after trying many competitors (M50, HD280, HD555, K240S, DJ100) I finally decided on the Shure SRH440s and am reasonably happy with that decision based on what I've tried so far (though I do find them a little bright and would prefer a wider more open soundstage). My quest so far is documented in this thread: http://www.head-fi.org/forum/thread/527533/my-budget-headphone-odyssey-hd555-vs-srh440-vs-k240s-vs-dj100 However, I've been camping out on head-fi constantly for the past few weeks and in my endless research have come across these other two budget closed headphones that sound absolutely phenomenal according to some reports. So before I give up my search and settling for the 440s (I like them, I really do!) I just thought I'd just see if anyone thinks one of these other models would be a vastly superior headphone for my needs. I'm especially interested in the Fostex T50RPs though I'm not sure I can drive them sufficiently and am not sure how much modding would be required to make them live up to their potential. Music: Large collection of mostly rock and jazz of many varieties with some old school soul/funk, library music, vocals, country, blues, folk etc. mixed in. I don't listen to much electronica, hip-hop, and other contemporary bass-heavy music but I do appreciate controlled, impactful bass as long as it doesn't color the rest of the sound as I found with the M-50s. Some of my music is poorly recorded and/or poorly sourced so I wouldn't mind a "forgiving" headphone though I do want at least as much accuracy, detail and clarity as the 440s. Usage: I will be using these all day at work so I do want a phone that is closed and comfortable (I wear glasses while at work and the 440s are bearable but not the most comfortable phones by any stretch). Portability is a plus, but not required. Amp/Dac: I do not currently own a headphone amp but am planning on purchasing a budget amp/dac for use with my work PC. I am looking at the FiiO E7 and possibly the uDac-2 (other recommendations under $100?). So again I'm not sure that this will work with the Fostex or not. Can anyone offer an informed opinion on the relative quality of the Fostex T50RP or Fischer Audio FA-004 compared to the Shure SRH440? Thanks for any feedback!!
