Seeking Expertise in Interpreting Measurements of an Interesting DIY Gold Diaphragm Planar Magnetic Headphones

[Sha1rholder]

Recently, I acquired a pair of DIY open-back full-size gold diaphragm planar magnetic headphones (similiar with Hifiman HE-6) and had the opportunity to measure them in detail. These measurements include impulse response, window, energy time curve, RMS level, smoothed RMS level, group delay, smoothed group delay, and relative level at 1.00000 kHz.

I sent these headphones to the Fiio Audio Team for testing, but I lack the expertise to interpret the data myself. Now, I humbly request assistance from ASR community to help analyze these measurements and provide insights into the headphone's overall performance.

I've attached a zip file including measure result. Thank you in advance for your expertise and insights!

Hi @Sha1rholder! Welcome to ASR.

For the correct interpretation, we'd have to know which measurement rig was used to create the measurements.
Any ideas?

Also, your DIY headphone looks a whole lot like the commercially sold NAN-7:

Thanks! Yes, the headphone I mentioned is NAN-7. I'll check this thread.

It's a DIY headphone like early works of the ZMF before ZMF reached scale. Its sales are significantly lower compared to major brand headphones but has a very good reputation. Therefore, Chinese audiophiles who are its main customer base, as well as its creator 阿南先生, consider it a DIY headphone.
