I have slightly unbalanced frequency response between my left and right ears, and with spatial audio center tends to the right. I’m an audio engineer so I’m especially sensitive to any shift in image, non linearities, etc. I tried Headphone Accommodations both with balanced tone and audiograms. The amount of limiting/compression is unbearable to me. Hiss is amplified well above acceptable signal to noise ratios, image is more shallow, losing significant depth of field, and audio just sounds distorted. I’ll apply classical eq at times as this has a similar effect as balanced tone settings but without the excessive processing and resulting distortions. I find this eq setting will clear up lower mid veiling, but it does scoop out a significant chunk of of depth of field, though it does reveal finer articulations in mixes. However, I’ve been depending more on the adaptive eq and headphone positioning. Balanced tone is agresssive on weak setting. On strong it distorts all aspects of the audio—harmonic, image, depth, dynamics, noise amplification, etc—that I find it unlistenable to the point of being acutely disturbing. Hopefully the new iphone will allow for true high res when wired, and updates to the apm and iPhone will allow for high res Bluetooth. Apple Music now providing high res and Atmos masters while their flagship pro headphones being incapable of playing high res from the iphone, wired or Bluetooth, is confusing. IMO allowing for true high res will make the greatest difference re eq and balance, namely that it should be unnecessary other than personal taste. But in this case, where high res will provide superior imaging and depth, one should be even less inclined to compromise it by using limiting and whatever processing is being used by Headphone Accommodations
