The BEAN® can provide that one click of clarity. As a personal amplification device–also known as a Quiet Sound Amplifier–The BEAN features a built-in sensor that automatically adjusts to the surrounding noise level. It amplifies soft sounds, while keeping the volume steady on louder noises or even reducing it for extremely loud sounds such as fireworks or the strike of a drum. Moreover, it boosts soft high-pitched sounds heard in speech, which helps provide clarity for conversations, particularly in less-than-ideal listening environments.
