Also, USB-C is the future. BUT they didn't support multiple devices, and I love that feature in my Sennheisers.
I've been using the Sony's for about an hour trying to decide if I can forgive this, and I'd gotten myself to "well, I can always use the 3.5mm jack with my laptop, and Bluetooth with my phone".
Then the battery died. No big deal, grab a USB-C cable from my desk and plug it into my laptop. AND THAT'S WHERE IT WENT WRONG. 2/?
