I've been asking myself the same questions some time ago and after lots of buying and testing (and some reading as well
) came to the following conclusions:
- It once again proved that there is no "best" headphone. Each has it's strong and weak points, some more of one than others ...
- Closed headphones are generally still
a lot behind their open counterparts and pretty much all leave a lot to be desired.
- Price/performance ratio of TOTL closed headphones are even far worse than TOTL open headphones, actually pretty ridiculous what TOTL closed cans cost considering the sound quality they deliver (at least in my opinion). All those 2000$+ closed TOTL phones not even sound as good as a decent 400$ open headphone.
- Basically the only reason to go closed is because of the need for isolation / limitation of sound leaking. However over ear closed cans all isolate really bad compared to iems, which kind of proves them obsolete.
- Of all the closed headphones I've heard the HD820 is probably the one with the least flaws - that is if you are willing to pay 2400$ for a headphone that sounds worse than the HD800, which can be had for about 1k$.
-> All in all I came to the conclusion, that closed over ear headphones like the ones you mentioned basically hardly have have a "raison d'être" - because if you don't need isolation open headphones are much better - and if you need isolation, IEM's are isolating much better and therefore are preferable in all noisy environments.
There is really no point in having better sound quality if the noise around you overlaps it all.
The only place I could see closed over ear headphones to be of much use are basically in a studio or if you're fine to have an expensive and worse headphone "just to disturb your spouse/flatmate/... a little less while sitting on the sofa together."
