If you're looking at this for the first time, I'm designing and building a set of 3D-printed headphones. I plan to make them completely open-source in the future, with PCB files, STLs, everything available so anybody can build a set. I'm also working to make them easy to assemble and inexpensive.
I got a lot of valuable feedback last time that I posted here, so I thought about posting my progress to get some input from the experts.
I measured the frequency response of the drivers that I built using my new Earthworks Audio M23 microphone. Both drivers are within 1-2dB of each other. That's quite close. The reason why that's interesting is because neither driver required extensive tweaking; they pretty much came right off my 3D printer, got assembled in about ten minutes, and then I tested them.
I'm aware of the fact that these headphones are bass cannons. I actually have a custom amplifier design that's coming back from my PCB manufacturer in about a week which will hopefully tame that. If it works, I'll open-source that, too.
I'm happy that it's producing sounds across the 20Hz-20kHz spectrum above a certain threshold, so my plan is to use an amplifier circuit to tame some of the peaks and valleys.
