Surround headphones for big heads?

[Angilion]

I was thinking of buying a set of the Altec Lansing surround sound headphones on offer this week. I'm after a set of surround sound headphones for late-night gaming and these seemed decent kit. Reviews confirmed that...but 2 out of the 3 reviews I looked at mentioned that these headphones aren't a comfortable fit if you have a big head. I do have an unusually large head and I have not yet worn a pair of over-the-head headphones that are comfortable for me. They all press hard against the top of my head.

So...does anyone know of some surround sound headphones under £50 that expand to a larger than normal size?

The reviews I've seen rate them as better than stereo, but far short of a proper speaker system. You have three different speakers on each side, but they are too close together to give more than a little spatialisation.

I was thinking of trying them as an interesting gadget. The sound quality would be good for headphones, even if they were very little more than stereo. Better than annoying the neighbours at 2 in the morning with my speakers.
