BackBeat PRO supports AAC and aptX, but OS X, by default, uses SBC. You need to download Hardware IO Tools for Xcode and use Bluetooth Explorer to enable those codecs.
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.
