For the lucky few who are testing the headphones - perhaps some suggested scenarios can be posted here.
I think it’s important to note sources, cable types and material, audio source etc as in today’s internet age, it is hard to identify is it one’s source or equipment when things aren’t “right”. Spotify at 64k plus a $3000 headphone may or may not be any good (I’ll never know!), while the $3000 Sony audio player loaded with mp3 files may or may not be decent. And so:
I’m curious about cabled vs wireless sound quality.
Bluetooth drop outs.
How the cups stay or don’t stay during various head movements (and NC).
How does it fit w glasses or even a hat.
Distribution of weight of the headband.
Is anyone planning to fly during testing? Use a train?
Results using YouTube vs iPod vs computer vs a fancy audio player.
Bag test - how do they hold up in your backpack, purse, or folio
And perhaps a @Konstantinos appropriate drop test?
Battery life testing with various criteria.
