What headphones were you comparing to?
Not all people choose to hear sounds the same way, so you may just be one of those people that cannot pick up the differences. I also believe its probably some selective hearing, you bought some expensive headset and want them to sound as good as a high quality headphones.
Depends on what you need, I haven't been reading the whole thread. I just skipped to the last page and some some misinformed comments.
I personally recommend the ad700's, I own them, they are open headphones but provide some of the best soundstage and separation on the market.
If you need a little more bass, hit up the m50's. There are other great brands as well seinheiser, akg, etc. Let me know what you need.
AKG 701's are a great set of headphones, I actually plan on upgrading to those next. I hope you got an amp or one built into your soundcard because those have a lot of resistance.
i will listen to some music too (hardstyle/hardcore, if that matters) but i mainly care about the gaming.
I really liked the 7.1 surround on the g35's but thats not really that important since i dont really play much FPS anymore.
They have to cost max like 150-200$. also it cant really be open headphones
