Playing with good headphones on does make a difference :rolleyes: I was wondering what audio gear has everybody got?
I have AKG K-271 MKII. Essentially they are sealed studio headphones, so they might not be as immersive or subwoofer-y sounding as hi-fi headphones in the same or higher price range. But they do actually sound extremely well and have excellent stereo imaging - the latter helps immensely on JO because the sounds are very directional. So if you are playing on a server with tracers off, or if you are flanking and do not see tracers because the gunfire isn't directed at you, it is still easy to locate the shooters. And they are comfortable, too. I got them for 166 euro at Thomann some years ago. If you are looking for good-sounding sealed headphones, they should probably be your choice.

I'm not fan of loudspeakers till I can afford a really expensive setup, so at home I just have a pair of cheap crappy ones :D
