ok, time for the write-up
>sound quality
Matches the 600 series very well, as intended, and even in the low latency mode. You don't get those top end compression issues like on most bluetooth headphones when using SBC and the like. Plugging the device via USB doesn't appreciably increase the quality and has the same kinda shitty implementation that Sonova (consumer senn) has had since 2015 last time I bought a momentum. Basically; Wired aux >>> wired USB.
>ANC/transperency mode
not enough mics for wind rejection, so it goes in and out with wind "adaptive mode" on. These are peak for office type noise (I was just in a copy room for 8 hours the past two days and loved they came before work). The transition between ANC/Transp is by pinching the side, which gets annoying (volume is like, 3 swipes, where transp is like 7) and while you can use it to overhear people, it won't replicate an open-back. Use the double tap pause to talk, or pull out an ear to auto pause.
>bluetooth quality
The dongle is, like, the best thing in the case besides the headphones, I cannot understate that. no need to pair if you can plug in a USB c port. It looks like an audio interface to the PC, and you can disable it auto switching to the headset mode. It's a better interface than the USB connection due to the latency/communication switching options too. There's a whole manual to play with (or you can get the windows menu driver). Unplug if your headphones are asleep.
As for the headphone bt, no complaints, it could have a better switch to 96kHz mode, but you could just keep it on and eat the battery life when out and about, multipoint to your phone and the dongle, all you need. Went across half a building without dropping connection too.
>build
All plastic as expected, but good senn plastic, hate the inside of the pads, but I think it's plastic bags for bass or smth. Can't fold and sits weird on broad shoulders, not a major hit.

kino as advertised, crossfeed is nice 2
