Build Your
Own Sound.

A field guide to building headphones you can trust your ears to: how drivers make sound, why enclosures behave the way they do, and how to measure, tune, and prove the result.

Who is writing this

MakerPhones is the open-source side of Warren Labs, my audio lab. Warren Labs is where I research how headphones work. MakerPhones is what happens when I give that research away for free: the full build manual, open files, and a pair you print and tune yourself.

I'm Jamey Warren. Twenty-five years in audio, from Grace Design to HeadRoom, now designing the Daily Driver in the open with AI as a design partner. Every chapter in this manual comes off that bench.

From the bench

Daily Driver

An open-back headphone, designed in the open with AI as a design partner. Follow the spec, the prototypes, and the dead ends as they happen. The measured curves land once there is hardware to measure.
