Hello, I have only recently found out about Head-Fi and the wonderful world of audiophilia, and I was wondering if there's anything I can do to improve my listening experience without having to spend too much. I am currently using a pair of Roccat Kave 5.1 headphones that are probably mediocre at best for music, and not a huge improvement over normal stereo headphones for gaming (their directionality is only very slightly better than most other headphones IMO), paired up with a Xonar DG sound card.
I mostly listen to pop, rock, smooth jazz and a bit of dubstep from time to time. I was considering getting the Sennheiser HD 558, but I'm still a bit hesitant because of all the reviews I've read of people complaining about how inadequate the bass is on the 558's. (I am not a basshead and I do realize there are lots of other factors I should be considering other than the bass.) I also don't think I'll be doing the foam mod anytime soon. Are these headphones good enough for those genres or should I get something with a little bit better sound quality without going over my $200 budget? Any feedback would be greatly appreciated.
