How badly do they leak? Strongly considering these for my Dolby Headphone/Surround gaming set up, but I usually play at night while my GF is asleep in the other room. Will this be an issue?

I own the Superlux HD681s, a different brand of semi-open Superluxes. I found that they do leak a lot of sound at high volumes, but are pretty quiet at lower ones. I feel like the CAD Audio HM310 is more suitable for you in this case -- it's a rebranded Superlux HD669, which is a closed Superlux which should leak way less.

Funny thing is I have the CAD-MH310s in my shopping cart right this second. I was under the impression they were rebranded 662Fs and not 669s. Do you know which it is for sure? I have read better things about the 662Fs than the 669s...
 
Unfortunately there are so few reviews on the MH310s (zero on Amazon) so it makes me a bit nervous...

I'm sorry, they are rebranded 662Fs and not 669s.
