Hmm, I actually am considering buying bassy over-ears, because all the over-ears I have are pretty neutral/studio sounding. I game a lot of singleplayer story-games and sometimes I feel that a bit more bass would be enjoyable for explosions, gunshots etc.
Thanks for the recommendation, never heard of SIVGA :)
I'd suggest the SV021 if you want bass, or the SV003 if you prefer the flatness of studio headphones like the Beyers.
I use them with a Sony Walkman DAP: best money I've ever spent!
Good bass matters for some styles: the SV021 is better when I listen to say Моргенштерн
