Beats’ update app/system is royally broken, or they’re intentionally preventing users updating their products. After learning about different firmware versions for Beats Studio Wireless, I’ve contacted @beatssupport, but they’ve responded with a ‘nothing to see here’ response.
I’ve just bought a NWZ-W273S to listen music while swimming training. While it’s extremely easy to add songs (just drag&drop in Music folder), updating to 1.10 firmware proved to be impossible. It didn’t work on Mavericks, XP or Win7.
