Labs

Measurement, correction, and a line of audio tools, built solo from a desk in Montana. I'm Jamey: twenty-five years in audio, soldering benches at Grace Design, then HeadRoom as CEO. Now I measure headphones on my own bench, publish what the rig says, and build the software that puts it to work.

AUTHORTHE ART AND SCIENCE OF HEADPHONE DESIGN
THE WORK · BUILT SOLO

Built in the open.

Products I took from idea to working software myself: the DSP, the interface, and the calls about what ships. Level is shipping; Attune and Tone Farm are in free beta.

THE BENCH · MEASURED HERE

We measure headphones.

Every correction you can buy is built from somebody else’s sample of your model. Send yours and get the curve of the pair actually in your hands — published either way, flattering or not.

SEND ONE IN

Your unit, on our rig

Measured on a miniDSP EARS Pro, labelled by rig, back to you in about a week — and it gets a page in the Archive, credited however you like. Unit variation is real, and your pair’s exact curve is what Attune turns into a personal tuning.

WHAT I DO · THE SIGNAL CHAIN

The work of product, end to end.

Every product runs the same chain, idea to shelf. Pull me in for one stage or the whole path.

SOURCE01

Find the signal

What's actually worth building: the real problem, the honest market, the thing only you can pull off.

SHAPE02

What's in, what's out

Settling the feature set and holding the line. The best calls are usually the things left out.

ROUTING03

Who it's for

Who actually buys it and why, what it costs, and the story that lands it in the right hands.

OUTPUT04

Get it shipped

Prototype to production. Hardware and software, sketch to shelf, including the places it tends to go sideways.

MORE FROM THE LAB

Two more products, two different product calls: a manual and an app. Click either for the detail.

Who you'd be working with

Jamey at the Warren Labs desk

I got my start at Grace Design and went on to run HeadRoom as president and CEO. Over 25 years I've shepherded audio hardware from prototype into production, built software, produced records, and stayed close to the music the whole time.

The work sits between the engineering and the music, knowing enough about both to push a product toward something people can feel. That's been the job for a long time, whatever the title on the door happened to be.

The Art and Science of Headphone Design

I wrote The Art and Science of Headphone Design, a bench manual on how headphones actually work, from driver physics to measurement and tuning. The full reference is free and open at makerphones.com. There's also a print and Kindle edition for anyone who wants it on the bench.

1997 · GRACE DESIGN01

Employee #1

Production, testing, repair, prototyping, and the automated measurement system the gear was tested against. Two founders and me, to twenty people and gear in studios worldwide.

2003 · HEADROOM02

VP Ops → President & CEO

Relaunched the entire headphone-amplifier line: every model from concept through prototype into production.

NOW · WARREN LABS03

Building in public

An independent line of audio tools and an open headphone field manual. Running the whole product chain myself, in the open, so you can see exactly how I work.

ALSO AVAILABLE · FIXED FEE

Need a second pair of ears?

If you’re building a headphone, I’ll read one from the outside — measured, listened to, and written up. Occasional work, taken a few times a year.

THE OFFER

Headphone Design Review

Send me a prototype or a shipping unit. I measure it, listen critically, and deliver a written report on what the design is doing, what it's trading off, and what I'd change.

FEE$4,500 fixed
