Sound World Solutions offers a return period of 45 days (longer than most), giving you more time to test the device before deciding whether it’s right for you. The CS50+’s battery life is up to 12 hours, making it the only Bluetooth-enabled PSAP we tested that can last for a full day of use. A Bluetooth connection allows you to listen to music or take phone calls with the device.
The app also offers a quick hearing test to help you figure out which settings work best for you.
Unlike most of the competition, the CS50+ allows you to program it to fit your specific hearing needs: Using an accompanying app, you can adjust the volumes of the treble, mid, and bass frequencies separately. If you’re interested in trying a PSAP, we recommend the Sound World Solutions CS50+, which improved sound perception nearly as well as a hearing aid in an independent sound-booth test that researchers conducted in 2017.
