Hi there, I actually bought the Saitek Impact. They are pretty good - very good for only 10 quid. They are not exactly comfortable - for me - for long stints, but I am comparing them with BOSE headphones that I use for my iPod and that is not fair as they cost shed-loads.....
It seems I have low tolerance for any degree of 'pinching' - I need low pressure - maybe I have a wide head??? Others report the Saitek Impact as very comfortable.
Hope this helps. I plan to stick with them for now.
