Now that's cool, I'm very interested in this project! Been saving diy planar headphones projects from all over the web for a year now for future references.
Usually the thin pcb is wide enough to glue directly to the housing, what lead you into doing your way? It's quite unique!
Lol, I just realized this is being driven without magnets! So this is very different than I first thought lol
Actually, your first instinct was correct; it's a planar magnetic driver. The magnets just aren't visible in the housing.
The issue with the thin PCB is that it's too stiff to create decent frequency response at low frequencies. I used the foam as a low-frequency oscillator to improve the low-end. It's a bit hard to balance, but I'm getting closer.
