Basic sound still works with this on gigabeat F. I don't know if the bass and treble cutoff settings work, you'll need someone with better ears for that

I tried the v02 and everything seems to work on M:Robe 100. Basic sound work, bass settings too. Treble does something but I don't know the expected result so I can't tell if it's correct or not. I didn't try to put the sound at maximim or minimum volume however.
