These bluetooth headphones look great, sound awesome and can be built using 3D printed and cheap, readily available parts.
They have volume +/-, track skip/back, play/pause buttons and a microphone to take calls.
To build them you need a 3D printer, soldering iron and basic tools. A heat gun is desirable.
For more comprehensive build instructions see www.homebrewheadphones.com There is also a simpler to build wired version.
I hope you enjoy this build!
