[QUOTE="Scott Helmke, post: 47165, member: 96"] Re: IEM testing jigs I finally got around to trying to build something. It ended up being absurdly easy to get usable results, not high fidelity but plenty good enough for testing. I took a scrap of plywood, and drilled a hole through same diameter as the Shure nozzle (1/8" drill bit), and redrilled most of the way through for the measurement mic (Earthworks M30, 9/32" drill bit). Stick the earbud into the small hole on one side, and the measurement mic into the other. It's a decently snug fit but not very tight. Plug the earbuds into an iPod playing music, plug the measurement mic into a mixer with headphones. I had to turn the input channel bass knob all the way up to get decent lows, and of course it didn't sound especially flat. But it does work, and aside from futzing around finding the right drill bit sizes it took all of 5 minutes to make. [/QUOTE]
