The Wooduo2 is something that's really only suitable for bassheads. The GR02 is bassier than the VSD1 by a margin, but the VSD1 is not lacking in bass compared to a flat/neutral sound. I quite like it.
Is that $20 for a bulk-package MH1C? If so that's not too far off what the US prices were before they got very popular. It's a darker, warmer sound compared to the VSD1, for example, but hard not to recommend at this price even with the crap cable.
PS you might also want to try a Philips SHE3580 or SHE3590 - they're very inexpensive and close to the GR02BE in sound quality.
Will it make sense to get both the MH1C and the VSD1?
