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...
- Same here. But we can sure find a friend or even pay for the 3d print service ;)
Have them, they sound pretty good. I haven't measured them yet.
- Did you print them yourself? How comfortable are they?
  
  Nope. Ordered assembled. They're very comfortable for my head.
- Do you have any other headphones you can compare them to? I'm interested in buying them, but there aren't many reviews available.
  
  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. 🤭
I want to buy a pair just to support this kind of thing. It's pretty cool.
My boss is going to be out of town for 3 weeks so I may just use the office printer to make this happen.
this looks sick!
ploopy are so neat.
I hope they make a wireless version of the ploopy mouse in the future.
I gather the audio quality on these headphones is very impressive but I don't have a pair to confirm that with.
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.
- But no turbo encabulator? That's quite a bold design choice.
  
  It would save on a lot of the discrete components used, I am not a fan of running open-loop voltage supplies.
I have no idea what planar magnetic means, but it sounds impressive.
- How to Geek has a good write up.
  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!
Really cool seeping ploopy.co expanding their offerings. I've wanted to get a Ploopy trackball for a while now.
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
