I want to upgrade my full-size cans; Open or closed are fine with me - I don't really have a preference, but open will obviously have an advantage in the soundstage. I like neutrality and I listen to classic jazz, rock, classical, and I really enjoy acoustic rock/folk. Not a basshead at all, but I do enjoy a bit of rumble once in awhile. I certainly am not averse to some tight, controlled, and impactful bass. I do like detail and a large soundstage, but I don't tolerate sibilance very well at all. My budget is a maximum of $300. I currently have Koss DJ100s for my full-size headphones and I do like them. If you have any good ideas, let me know. I'm considering Beyerdynamic DT 880 Pros (250 Ohm), but I want to get a few more recommendations first. Thanks, y'all.
You and I share some genre similarity, especially in the area of popular music. The mid-centric DJ100 is a good entry level can for most of the music types that you enjoy.
The DT 880 is a great can. It is analytical and unforgiving of crappy tracks--so make sure you are OK with that. You should also look into the AKG Q701, Senn HD 598 and Sony MDR-MA900.
