I purchased my SportEAR hearing devices. As a result of a work related injury, I am hearing impaired. After trying several expensive pairs of hearing aides with unfavorable results, I decided to give SportEARS a try. They provide me with the amplification that I need and unlike the expensive hearing aides, I do not have to remove them when talking on the phone. The size, comfort and capability of these quality units are exceptional. I have since purchased an additional pair as a spare. Jill and the staff at SportEAR have provided me with prompt and courteous service. My wife highly recommends this product!
