The Sound Check is a free online hearing test. It takes about 5 minutes to complete. And you can retake it as many times as you like. At the end of the test you'll be shown your personal hearing profile, which looks similar to an audiogram. You'll also be able to hear the difference between a standard call and a call adapted to your hearing by our Clear Call technology.
