I have a pair of cheap (£30), Chinese Bose knock-offs. In terms of performance they're pretty much indistinguishable from a pair of genuine Bose I tried, but to my tastes not quite as good as a pair of recent Sonys. I strongly suspect that they're almost identical internally to Bose. Mine are unbranded, but search for "JH-ANC804" and you'll find them.
