My perceived differences between Q-pad-1339 and Beyerdynamic 880s

I wonder how they compare against the beyerdynamic 880s though, price wise they are around the same but you do get the mic with the QH-1339.
My Q-pads broke down yesterday evening, after a short but passionate relationship. I then considered different options, since I knew our local retailer was out of Q-pads (I was definitely ready to put another 320 euros to by a fresh pair), and accidentally stumbled upon this forum because of SieB's comment probably. Regretfully I wasn't able to find a definite answer, until today, when I then took upon me to buy a pair of 880s instead, as the Q-pads were sold out and I'm not fully comfortable with headset mics.
I have to say, after getting over the fact that I now have to buy a dedicated sound card, as the 880s with 32Ohm impedance and 96 dynamic range seem to be sucking my AMD integrated sound card completely dry, I have not regretted my decision one moment: Only now can I fully say I understand why for example Bruce Springsteen's "Born in the U.S.A" has been better appreciated than the earlier "River"-album - his voice simply matured during the few intermediate years so much.
Where the Q-Pad exceeds the 880s in my current configuration is bass and isolation from background noise. The Q-Pad had a much deeper bass, as it had been designed to be used with integrated sound cards - to create an equally robust bass, the 880s require an amplifier. When I got direct audio out with an optical cable and plugged the 880s to a Harman Kardon amp, however, the bass came out perfectly. The Q-Pads also clearly put more effort into getting the bass out loud, since when listening to classical, strings are displayed more nuanced with the 880s. The Q-Pads also block background noise better: the 880s are only half closed, giving some noise through. The cup form of the Q-Pad also seems to have created a slightly superior 3d environment, essential for those fps players on top of their class - however, being a casual fps gamer and more of a strategy lover myself, I don't really miss that so much.
So all in all, for me it seems the Q-Pads were a kind of a gateway drug to audiophilia and the superior music experience provided by the 880s. But if you're only buying a dedicated gaming headset and plan to go to a lot of lanparties, then I'd recommend the Q-Pad for you.
