Good to know there isn’t noticeable distortion then. The frequency responses I have seen look good to me. I definitely hope to see some in depth measurements come out for them! I assume some audiophile creators are getting their hands on them, and I would expect to see reviews in the near future.
Here’s another bad measurement I did just now on my EARS. Bad because there are known problems with the EARS like the giant hump at 4.5K which is not due to the headphones but a resonance in the “ear canal” of the EARS. The red is SRH440, and the blue is the Ploopy. One of the graphs has psychoacoustic smoothing applied. The other has no smoothing.
There’s a hump at 43dB which is EQed down and a trough at 420dB which is EQed up. They get a lot better in the psychoacoustic view. Again, ignore the gore at 4.5K, that’s strictly a measurement problem.
My noise floor is bad so the overall noise level is useless but humps in THD are somewhat useful. Here it is:
There’s a small hump around that trough at 420. Nothing ridiculous overall. The gore at 4.5K is again due to the measuring equipment.
