The X-1 is basically that though only the shell is Beyer. I really wanted a way to adjust the driver to virtually any depth at will, this is what's come of that (along with comfort and eventual good looks).
The Cherry Bombs are a one piece, all wood deep chambered, pre fitted with a top class Grado driver that will fit on an unmodded Grado band. They will/should sound better than modded HF-1's. I may possibly offer them just like that (and complete), no cable, no band, just slip them on your current band and plug in a cable. Then again, I may just keep a pair myself and leave it at that.
Both are just proto's that I thought I'd share. I also am going to make an electrostatic/dynamic combo which can probably double as a surround sound can. Speaking of surround, that proto pair I made out of an old Pioneer quad set is too good not to expand on one of these days. Soundstage almost too good for headphones
