Renting a MiniDSP EARS or similar to measure headphone frequency response?

[dstarr3]

I'm pretty poor at EQ'ing my own headphones unless I have a FR graph to start from. Some of my headphones have been modded, some have very transformative third-party earpads on them, etc, which makes the FR graphs for these headphones in their stock configuration pretty irrelevant and thus not a very reliable starting point for tuning my own EQ.

Thus, getting my own device to measure the FR of my uniquely configured headphones would be pretty handy for me. Problem is these are usually expensive devices and I'd really only need to use it once or twice and then it'd get shoved in a closet for the rest of time. So spending the money to purchase my own doesn't make any sense.

Though, renting one for a weekend or so would be totally reasonable, if there are any outfits that provide such a service. And that's my question: Does anyone know of any places that provide rentals for this kind of equipment?

The MiniDSP Ears may not provide the accuracy you need :

The results you'd get may lead to some degree of misinterpretation.
Industry standard rigs are insanely expensive. I personally don't know whether or not they can be rented.

Since I assume that you mod headphones for your own benefit, I am tempted to suggest to you to perform measurements of headphones on your own head with various microphone systems. For measurements above 800 hundred hertz or so it's not easy, but if you're quite methodical the results you could get would be more accurate to what you actually hear.
Something like this can get you started quite reliably below 800 hundred hertz or so and may provide some interesting information for relative measurements between some headphones up to a few kHz : https://www.soundprofessionals.com/cgi-bin/gold/item/SP-TFB-2
Blocked ear canal entrance measurements may also provide some valuable information. Not quite as easy to do well (it's really important that the mics sit at least flush with the entrance if not recessed), but for me so far they've proven useful up to around 7kHz.
