Found 7th Feb 2010
£10 for 2 mics seems like a good deal. I picked them up at the ASDA living store in Oldham (Elk Mill). Were a few more on the shelf. They are GameOn branded. Can't find the exact ones on the internet but they look like those in the picture. The box says they are compatible with rockband and singstar, but not lips. No mention of guitar hero.
