These look nice! I have also been making my own headphones. I recently posted a twitter thread with build instructions if anyone wants to make them. [1]
Notable difference is that mine are simpler to build, though less integrated. I use an off the shelf bluetooth to 3.5mm adapter rather than one of those integrated boards (I did recently buy an integrated board to test out). The off the shelf bluetooth adapter just plugs in to the short 3.5mm cable I build in to the headphones, which has the advantage that you can make them wired headphones with a simple extension, which sometimes has its use. Anyway take a look!
I very much appreciate that your design incorporates the ability to use them wired as well.
While I’m out/in transit, of course there’s nothing particularly terrible about Bluetooth.
When I’m at home, however - I produce music a lot more than I consume it.
I also mainly consume music at home on my record players anyway, which obviously I don’t use Bluetooth for.
As any audio producer will tell you; the latency introduced be even the newest Bluetooth standards makes producing music in a DAW a frustrating experience at best.
I love the ‘best of both worlds’ headphones with optional latency-free wired support. I can take them on the go and use Bluetooth on the bus, I can connect a wire at home; and produce in bliss.
I would absolutely love to create my own headphones from the ground up sometime, choosing my drivers and cushioning carefully, and ideally modelling/3D printing my custom design, based on taking measurements of the shape of my head and size of my ears. (I prefer over the head headphones as even the most comfortable buds tend to hurt my ears after a short while.)
Aww I’m glad you like the design! Feel free to use mine as a jumping off point, it’s all open source and I just want people to benefit however. Onshape is free and I’ve got like six different headphone designs in the Onshape design files linked in the thread.
But yeah I use the wired mode a lot. On one of the headphones I got a TRRS splitter and added a microphone and I can plug the TRRS cable into my Xbox controller and use it as a gaming headset. It’s a very flexible system!
Personally, the next thing I would like is SDcard + USB mass storage support (+ USB sound card support to listen while plugged in), so one could upload a podcast and listen to it later...
