In the first vid above, the cheaper Fifine option (think it's a Fifine K669 5 V USB) didn't sound too bad actually. As pointed out, a drawback was the short stand as it would be very close to your keyboard and it doesn't have the noise cancelling efficiency you'd get with the other set-up. But for £31.74 I think it's pretty amazing, and combined with the Superlux HD668B should beat any £100 headsets for mic quality and get very close to audio quality, for less cost. If you like open/semi-open headphones that is.
