Simple Ear Premium fits in your ear and is protected from the wind. It's a good solution for bikers to keep hear the environment and stay safe! Here is some additional information on using a hearing aid in conjunction with a helmet.
Summary: Hearing aids can be hard to accommodate under a bike helmet, and sweat can cause problems as well. We have suggestions, but do not recommend ever reducing the liner foam and the protection of the helmet.
We are aware of several different problems that hearing aid users have when using helmets. Children are said to be hard to fit when using a hearing aid. Adults complain that when they sweat while riding, the hearing aid is affected. Those using bone-conductive aids or cochlear implants have a different problem altogether.
