Our friends over at digitalDJgear.com was kind enough to measure our V1 headphones. They can’t measure THD but can record response and impulse response, but for most people the frequency response is what’s most important. Here’s the testing methodology:
Tested with a program called Smaart and use an Earthworks M30 into a Sound Devices USBPre2. Used a Plastic Manequin head, painted it with a texturized paint (to minimize direct reflections as much as possible) and installed a measurement mic “in” each ear. Pink noise or a sweep is run through the headphone and then measures the resulting response with the mic. It’s measured against the reference signal which is smaart measuring it’s own output of pink noise (no DA/AD).
