Those look so rad. Huge respect to the person /people who put the work into making those. Makes me wish I had more 3d printing/fabrication knowledge...
I've got the closed back classics - SRH440, ATH-M50, MDR-V6. Subjective listening tests are not great in my opinion. The Ploopy sound great, but they also sound different due to being open back and the drivers being further apart. Do they sound great because they sound different? I can't tell. Their frequency response does sound accurate overall. I can't tell if there's distortion and how much it is. There was some distortion due to overly amplified input filter gain that I helped them fix a few months back. I can technically put them on my MiniDSP EARS and measure them, but the EARS isn't a great measuring fixture. The idea of sending them to Amir from ASR crossed my mind. 🤭
Was checking the schematic, nice notes! I would have sprung for a regulated -9V using a dedicated switched cap doubler chip (they're cheap, 1x of these to invert, 1x to double) and a LDO follower.
TL;DR - it's a different way to make sound waves that can be extremely responsive and low distortion at higher volumes at the expense of weight and a more flat response curve.
Just based on the name, I'd guess headphones with flat magnets. I never knew this was something I needed in my life. I'm tired of those spherical magnets controlling everything!
I wonder how easy it would be to modify these to get them to be clip on ear phones. Maybe the drivers would be a bit too big as standard to make ones that could conformably hang on your ears
