Headphone Measurement Rig

Last crawled date: 6 years, 6 months ago

DIY headphone measurement rig. Cost of this is almost nothing aside from filament. It is designed to use M3 copper brass inserts and M3 screws. As microphone, I used POM-2738P-R and small amplifier circuit. Schematic is listed in the pictures.
There is some result (frequency response):
