I used XM3 for 2 years on Linux, Windows, macOS and Android. I guess I used them for 4-12 hours a day most for most of these two years. I guess I spent at least 1/4 of this period with them on my head. And I dropped them many times, weared them during my runs on seaside in hot weather as well as walked in them inrain / snow.
They still work as good as new except for battery life, but this expected for device that had 500-1000 recharge cycles. I guess battery lost like 30-50% of original capacity.
PS: I only used Sony app a few times to update firmware and change settings though.
