Rolling Back Sony Headphone Firmware

A lot of users have complained that new firmware updates have worsened battery life or noise cancellation performance. Well there is now a way to reverse the update, using MrWalkman's MDR Proxy, the Firmware sidegrade tool.

Disclaimer: If you brick/break your headset, I do not take any responsibility.

The tool can be found on MrWalkman's Website HERE.

All of the instructions and links to the tools can be found in the link. The tool only works on Windows, so if you are Mac or Linux, you are out of luck. All questions should be directed to MrWalkman in the link above, since while he reads the comments here, it will be faster for him to reply on his own website than here.
