## What is CS Customizer?

The CS Customizer app allows users of Sound World Solutions' CS50/CS50+ Bluetooth Series personal sound amplifier, Companion, or Sidekick products to personalize their settings and control the device via Bluetooth link from their smartphone.

Under the "Personalize" tab of the app, an automated program will walk you through the steps in tailoring the performance of the listening device to your individual preferences.  This tab also gives you the option to adjust the baseline setting of your listening device to one of three preset listening profiles, or to your personal profile

The "Settings" tab allows you to select two additional environmental settings designed to optimize the performance of the listening device in specific situations.

Restaurant Setting emphasizes the directional microphone to focus on sounds coming from in front of you and provide rejection of unwanted sounds in noisy environments. Entertainment Setting provides increased low frequency response for a more natural, balanced sound at musical or theatrical events.

The app also provides an "Equalizer" tab to adjust individual settings for treble, mid, and bass frequencies for a truly customized user experience. You can also adjust the volume, similar to the volume button on the listening device.

Finally, the "Tools" tab gives you the ability to change the language of the voice prompts in the CS50+, Companion, and Sidekick.  You can also turn of the A2DP music setting if you do not use it and you don't care for the sound effects from the phone.  You can also access the User Guide for the CS Customizer from the "Tools" tab.
