About this app

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.

My previous review is out of date. Let's start over. I have been a satisfied user of CS50+ devices for about 4 years. I wound up using sort of plain vanilla settings, but I can hear voices much better when I have put the devices on. I do depend on the CS Customizer app. Now version 1.6.0 will not run at all. I can't say if this version previously worked. I tried to run the app to check settings and it doesn't work. I have done all the drastic steps for Android apps that crash, but no change.

Hi Jim, We rolled back our app to the previous versions so we can work out some bugs. I see you tried reinstalling the app. Can you please try one more time to ensure you have the rolled-back version? Thank you

Device had been working ok as long as you don't have a lot of background noise, but now the app continues to crash and I can't link the devise to my phone. I uninstalled the app and tried reinstalling, but now I get a message that the app was built for an older version of Android and may not work properly. No updates available. This message did not appear when I got the devise for Christmas, & I have the same Galaxy 9 Note. Too late to return now.

App is simple, but works fine on Android smartphone. Ear pieces mostly pretty good, worth the cost. Had trouble updating app, but after uninstall & reinstall, it works fine again. Do personal hearing test for best results. Equalizer and other functions work well. One fully charged battery doesn't last full day -- dawn to night -- need 2 for that. One lasts 12-15 hours. Bluetooth connects to most devices. Still having trouble with PC, though; prefer earphones with microphone anyway.
