I know that headphones have been discussed a lot, but I thought I'd ask again with a bit of a specific focus. I want to focus on cans used for tracking, so accurate sound is not a big issue. The sound has to be clean and clear, but if it is hyped or cut in some area that helps a player improve performance so much the better. To me the big issues during tracking are bleed and ergonomics/comfort. One problem is these tend to be at odds with each other. You get better isolation with heavy, tight cans that can be a pain to wear for hours. Anyway, I currently have two kinds of cans: cheap and cheaper. The cheap cans are in the $100 a set range: The Sony MDR-7506 and the Sennheiser HD 280 Pro. These both do a pretty good job on containing bleed. The Sonys are lighter and I find them more comfortable to wear. But I find that their hyped high end is tiring to listen to for a long time (and I don't need it playing bass). The Senns have a more pleasant sound to me, but are heavier and tighter. (I've always assumed they will isolate better with a loud headphone mix, so I've always given them to drummers that didn't have another preference. But I've never done any careful testing on this.) There are a bunch of candidates in this price range that I've never tried, so I'd appreciate people chiming in on these. I have several Sennheiser and AKG cans in the sub-$50 range that work fine. Some people like them because they are so light, but the real motivation for this post is that I was stuck with one with a flimsy cord that kept getting tangled last night as I switched from mixing to playing, so I'm going to get a couple more pairs of "better" cans. So I'm set with bargain cans, but if you want to post on that topic here I'm sure there will be interest. Also, if someone wants to make the case for more expensive models ($200-$500) as being a big benefit during tracking I'm willing to listen. But I've never tried any that were substantially more comfortable, and while the ones I've tried certainly sound better than the $100 models I don't see that quality helping me pick up a cue or establish a groove.
