This release does not have a Play Store Description, so we grabbed one from version 01.16.0002:

This is the official application for the Sony Stereo Bluetooth Headset SBH52. You must install this application to use the Stereo Bluetooth Headset SBH52 device. It allows you to search for new Google Play applications, change settings and enable/disable downloaded apps and much more.
Note: This application will not be visible in your phone's home screen. Access application settings via Smart Connect (LiveWare™ Manager), or via your phone's status bar.
