Sony ULT WEAR Firmware Update to Version 2.1.0

\

It appears that Sony is slowly addressing the Bluetooth vulnerability in their models using Airoha/Mediatek SoCs. The ULT WEAR is the latest model receiving the update.

Benefits and Improvements

• Enhances system software security features 

The update also includes all previous firmware updates, which I did not cover. Oddly enough 2.0.7 already seemed to addressing some of the Bluetooth security issue.

Version 2.0.7

• Improves an issue where ringtones may not be audible when connected to an iPhone
  Note: If you have encountered this issue, it can be resolved by either initializing the headset or using them to make a call after the update.
• Enhances system software security features 

Version 2.0.5

• Adds Quick Access support for Amazon Music
  Note: This feature may not be available depending on your country or region. 

The headset is on sale right now on Amazon, 30% discount. Thanks MrWalkman for notifying me about the firmware updates.
