I wear headphones for about 5 hours every work day. If these are more comfortable than the alternative, I’m very ok with amortizing the added ~$300 over the ~1000 hours of extra comfort just in year one.
This is a fancy way of saying "I'll pay more for nicer headphones because I use them a lot". Sadly the point above is that you'll be forced to pay more again and again thanks to the fact they are wireless only so you'll need to replace the batteries.
Who cares, $600 every 5-10yrs seems fine to me. These are computers on your head. I don't mind replacing the whole unit. But you don't even have to replace them entirely...Apple will replace the battery for $79. So if after 5-10yrs, you wanted to get the battery replaced, you can.
It's almost like people on HN have never bought noise canceling headphones - none of the top models have user-replaceable batteries.
