It’s no big secret that wearing in-ear devices, such as stereo earphones or hearing aids, can cause the ears to hurt over time. According to the engineers at Colorado’s Asius Technologies, however, this isn’t due simply to a poor fit or high volume levels. Instead, it’s caused by an “acoustic reflex,” that no amount of earbud-reshaping or decreases in volume will alleviate. There are reportedly ways of minimizing or even eliminating what’s known as “listener fatigue,” though – these include a flexible membrane, and even an inflatable ear-tip device created by Asius.
