My son and I got to try the Mysphere 3.1 headphones at the very end of the last day of RMAF, and we walked away very impressed. OMG we almost missed these! They were so much better than my previous re-cabled AKG K1000 that it's not funny. I was driving the K1000 with an SAC-KH1000 amp, which was quite powerful and it still seemed borderline in the bass region. My Eddie Current ZDT amp was too soft with the K1000, even though it can drive my HiFiMan HE-6. The Mysphere 3.1 CAN BE DRIVEN BY AN IPHONE 7+ WITH ADAPTER.
The Mysphere 3.1 are probably going to end up in my top 5 headphones of all time - they were smooth, detailed, refined, spacious, punchy, extended, and I could not find anything to complain about. You could make them sound more intimate and bassy by folding them in tight against the ears (well controlled and not bloated), and more spacious by folding them out (still tight, deep, and present bass).
There was only a very small change in the bass volume between positions, and very little change in bass quality. No, they still don't perfectly mimic the sound of a speaker's soundstage, but I think that it's the closest you're gonna get with a headphone, unless you have the Smyth Realiser sound processor (an amazing device). The headband is unusual when compared to other headphones, as the band sweeps forward towards your hairline instead of being just ahead of the crown of your head (no pun intended).
