Ploopy Headphones are pushing what’s possible with 3D-printers.

Ploopy Headphones come with a built-in DAC, amp, and EQ. And yes, it’s all open-source.

48kHz sampling rate. 16-bit audio depth. 16x oversampling.

The heart of the Ploopy Headphones DAC is a PCM3060, an extremely capable audio codec. It’s capable of up to 192kHz sampling and 24-bit audio. We chose a more modest audio quality, but the full power of the PCM3060 is fully available to you.

Powerful digital tuning, at your control.

The Ploopy Headphones EQ is powered with a hefty RP2040 controller. That means that you can tune the Headphones any way you like, with up to six digital filters of any kind. The only limit is your imagination.

Open-source. More choices. More freedom.

Source files for everything are available, for free, forever, without any limits

Complete documentation for assembly, modifications, and maintenance

A Few Words about the Ploopy Headphones

“They sound clear, clean, and detailed. The soundstage feels reasonably wide and spacious. The bass isn’t at all excessive, but they have better low-end chops than I expected; you can really feel these thrumming on your ears when you play something bass-y.”


“I just let my son listen to them for a few seconds and his first thought was “so these are what, $700?””
