You can use the BeHear and control its basic functions even if you don’t have a smartphone. However, if you want to make sure the BeHear amplification matches your hearing profile, we highly recommend that you take our hearing assessment using a smartphone and our app. The hearing assessment results will be saved in the BeHear headset, so you can use it later without a smartphone. The smartphone is also instrumental in fine-tuning the hearing environment in real time. However, the headset itself includes seven built-in control buttons that allow you to use it autonomously. So, if you want to use the device for ambient hearing only (not mobile phone calls or audio streaming from a phone), you do not need a smartphone.
