Is it a direct fit? The head? Does it stay in place well?
Let's see if I can shed some light on the situation (not my pictures):
While faces aren't compatible, the whole head is. Apparently Wave has gone into trouble of making the neck joint compatible with MMS3rd. HOWEVER EXTREME CAUTION IS STILL ADVISED WHEN TRYING TO EXCHANGE HEADS.
The fit is said to be very tight, also BQ parts are not likely to be precision-made so your experience may vary.
"Headphones" are removable and apparently reusable.
One can also mod BQ face to fit Arnval Mk2 head as an extra face. The mod is non-reversible (sanding etc required).Source
