$800 for a device that many people use multiple hours per day for a few years.
I doubt any other device comes close to a rate of $0.80 per day for the amount of utility you get from it. If you use it for 4 or 5 years, like I do, that goes down to as low as $0.50 per day.
Day 1 reaction was sticker shock, but yes, I see your point. If it's insanely comfortable, connectivity a breeze, and sounds amazing...yeah I can see it now. Most bluetooth on headphones with the blinking dot UX is horrendous so maybe people will pay the premium.
