## What it is
Ploopy Headphones is an open-source hardware project providing all design and production files to build a set of 3D-printed headphones, including a DAC/amp/EQ board based on the Raspberry Pi Pico. It includes GPLv3 firmware and CERN OHL v2-S hardware designs with assembly and programming documentation.

## Use cases
- build your own 3D printed headphones
- open source headphone DAC amp with EQ
- DIY headphones with Raspberry Pi Pico audio board
- customizable headphone firmware equalizer
- assemble open hardware audio gear at home

## When to choose
- you want fully open-source headphones you can print and assemble yourself
- you want hardware and firmware you can modify, with a built-in DAC/amp/EQ
- you enjoy DIY electronics and 3D printing projects

## When to avoid
- you want a ready-made consumer product with warranty and support
- you have no access to 3D printing or PCB assembly resources
- you need a permissive license for the hardware designs

## Facets
- artifact type: application
- maturity: active
- function: audio-processing, embedded
- domain: hardware, cross-platform
- platform: embedded, cross-platform
- tags: open-source-hardware, diy-audio, headphones, raspberry-pico, dac-amp, 3d-printing, equalizer, firmware, audio
