I received those print+ 3D printed headphones I mentioned a few years ago last year. The speaker module is small with that headband pass-through, but the audio quality is still surprisingly good across frequencies. Most troublesome points are that the headband is a bit weak and with the shape of the ear muffs doesn’t fully cover the ear well or sit stably on your head. It also costs a few hours to print all components but you are able to customize them which is worth it. I now have the JBL E-series and am happy with those.
