I'm looking for new all-purpose headphones (gaming, music [pretty much only rock music], and movies) in the price range of like $200, though that's rather flexible. I searched for at least a couple of hours here on the forums, and a lot of people seem to recommend the DT series of Beyerdynamic (770/880/990), and I still have a few lingering questions about them (though I'm not necessarily closed to other headphone recommendations). I've read many threads that compare the DT series headphones, though I haven't found them particularly useful because I don't understand the terminology used.
First of all, it may be relevant to explain the reason I'm looking for new headphones, as that might help with more accurately determining what's right for me. The reason I'm looking for new headphones is because I'm just sick of the Grado SR-225 that I've had for a couple of years, for several reasons. First of all, I find the bass lacking, but more importantly: they're the most uncomfortable headphones I've ever worn, there's occasionally a buzzing sound on the left side which I can only get rid of if I blow into the inside (forgive my terrible command headphone anatomy terminology :P), and the cords between the left and right side are constantly twisting.
I tried my brother's Sennheiser HD-280 headphones to compare with the Grado's. They were comparatively very comfortable, though I found the bass too overwhelming. I'm not nearly as good at describing sound as you guys are, so perhaps "overwhelming" isn't the right term, so let me use a real life example of what I'm referring to: I don't particularly like "theatre-like" bass; it just sounds too unrealistic to me. By the way, as for open vs. closed headphones, I didn't notice much difference when comparing them, so that factor isn't too significant for me.
Now, with the DT series, a lot of the difference between the 770/880/990, from what I've read, is that of the bass. If I found the Grado's lacking in bass and the HD-280 too overwhelming in bass, where might the three DT models fit on that spectrum; which is least theatre-like but not as weak as the Grado's? As for my gaming needs, I'm not a particularly competitive gamer, so I don't want headphones like the AD700 which have spectacular directional accuracy at the cost of
Also, I'm not sure what an "amp" is, though I don't think I have one. I figure this is worth mentioning, because most people on head-fi seem to have amps, so I'm not sure if not having an amp means that a particular headphone won't be a good choice any longer. I have a desktop computer with an ASUS Xonar DX sound card. Will I even notice a difference in quality between $100 headphones and $300 headphones given my setup and given that I'm not really much of an audiophile?
Finally, there are sometimes different versions of the DT models, especially the 880, in terms of their ohms. I don't know anything about ohms or what effect they have or anything, but I gather that certain ohms work well with amps and others don't. So in any case, I'm wondering if there's a particular ohm that suits me best given my ampless setup?
Thanks! Sorry I'm such a noob when it comes to this stuff :(
