Headphoneus Supremus
I'll let u know how it fares after I get mine. You're right that the bass isn't going to be prominent but it should be palpable as it's a dd. The upper mids and lower treble seem a bit hot based on graphs but we shall see how that translates.I have no experience with those sets in your post but massdrop is currently selling the JVC HA FDX01 @$250usd, which has three tuning filters to change sound signature.
It seems initial reviews are saying the timbre is the best part about it. I was sitting on the fence for very long but decided not to get it in the end as the FR looks like a subbass roll off and I'm a basshead unfortunately.
Btw, great efforts and good thread @iems0nly ...
