Indeed. My question arose more out of a logical train of thoughts (why would an individual with a significantly longer or shorter ear canal than standards would want an ear canal resonance peak at a different location when wearing an IEM vs. an over-ear or speakers ?) rather than anything...

It would require a longer post than what I have the time to write now, but Soundguys' measurements of the AirPods (in particular the APP2, perhaps the AP3 as well), haven't been properly primed and / or weren't made with the optical sensor triggered. They aren't valid. AirPods need to be fed a...

I wish !

May I suggest, unless it's already been done, and if your move to Android only is a consideration at this stage and not set in stone, to start with the APP2 and see if you like them ? The benefits are just too great if you stick with Apple's ecosystem. But if you're already seriously...

Indeed, but I'm specifically wondering about IEMs, since as you already measured and shared, they don't vary at the eardrum, with ear canal length, in a way similar to either loudspeakers and over-ears. Basically, a target for over-ears wouldn't need to see its ear canal resonance shifted given...

Thanks for sharing ! Have you had the opportunity to also test, with IEMs, shifting the frequency of the ear canal resonance (2-4kHz), not just the gain ?

Hopefully they'll be able to make the response more predictable past 1kHz, whether by passive or active means.

It's also, for the APM, largely related to HPTF, not HRTF. In both the APM and APP2 cases they're facing HPTF / eardrum HRTF mismatch issues (and possibly undershooting - on average ! - a bit the response in the 1-5kHz range to avoid any excess), but the underlying mechanisms for that mismatch...

It's possible, but it's also possible that it could be a coupling issue. While the Ace's feedback system likely makes them quite consistent from fixture to fixture (and head to head) below around 500-800Hz, it's quite likely to be like most other headphones of its kind above and vary quite...

Treble and fit will determine that for the most part. I own the Chu 1 and 2, and 7hz 1 and 2. I prefer the latter one among these, essentially because the treble response is less unpleasant for me than the other three.

Thank you SO MUCH for this. That's literally the n°1 feature I was dreaming to see in REW !

The system-wide renderer doesn't really have a way to select which content will receive the application of the personalised profile or not, as long as it follows some specific API implementations to enable Spatial Audio in the first place. If so they all go through the same pipeline and will be...

Unlikely given the wavelengths involved and the excess group delay Resolve measured in the above graph.

No need for a binaural renderer with speakers :D. I believe that the Apple TV receives in DD+JOC, but I have not looked into how it presents the data when using HDMI. In the case of the HomePods, IDK exactly who does what in the case of an Apple TV + HomePods setup. I think that's correct. I...

This isn't really an Apple-caused problem. AC4-IMS is a format dedicated to streaming pre-binauralised Dolby Atmos as two channels + metadata. As it is pre-binauralised, it's incompatible with many of Apple's features and preferred implementations - which with compatible devices are system-wide...
