picking up secondhand headphones this afternoon and I'm hypeed. I practically *live* with headphones on so the upgrade will be really nice (Bose QC35 gen1 to a Sony WH-1000XM4)
also quite neat how it does stuff like pause the music when you take them off, and has a feature where you hold your right hand over it, and it temporarily reduces music volume and noise cancelling a lot so you can hear around you
