I did just that (well not a full hour) in a reasonably quiet environment. Some 'measurement hardliners' tried to burn me on a stake for saying... This was 'the best headphone I ever heard'.
Sure... some bias may have crept in knowing what it was/costs but I just listened to 'effortless reproduced music' without ever wondering if this or that aspect could be 'better' and could compare it to the HD800S and the HD650 directly on the same music.
No tears to my eyes though. Just nothing to nag or complain about, other than the price and looks of the energizer.
Could I still enjoy other headphones... sure. I still do even headphones less than $ 100,- I can thoroughly enjoy.
A headphone that came somewhat close to this was the Sonoma model-1 but at impressive levels it distorts.
Still... a HD800 EQ'ed to a similar tonal balance (not necesarilly Harman acc to a standard fixture) isn't that far removed either and more affordable....
Here is the thing.
Your observations/reviews/impressions/measurements carry weight. Lot of it.
I would not burn you entirely (we need you ) but would, at least participate in the flogging.
I understand that SOTA do come at a price but $59,000.oo is robbery territory, especially when similar, perhaps better performance, can be had for perhaps 1/10th the price..
I am one of those not yet convinced by Sennheiser. I am also one of those who
like, as opposed to just accept, the Harman headphones curve. I need to listen to a properly EQ-d HD800s.. I am no longer searching for the best headphone, I have found it, the HifiMan HE6Sev2. I've heard/had some pretty interesting headphones, some in the >$5,000.oo, price range and with high audiophile reputation. To my ears and knowing, (THankfully!!) that my impressions
do not carry any weight (as opposed to yours
), The best headphones I've heard/had is that, the HifiMan HE6Sev2. Raw and un-equalized it is acceptable.. barely. Equalized to Harman:.. one superlative headphones, the best to me and currently at $400.oo at Adorama!!! (Jump on it , people, before they run out of stock./are discontinued. forever...)
Happy holidays!
Peace
