Almost all hearing aids are generally tiny stereo microphone/amplifier/speaker combinations. But not the NeoSensory Buzz. Conventional hearing aids include an earpiece. But not the NeoSensory Buzz. Instead, the user wears a chunky wristband, which “hears” sounds and communicates to the ears via the user’s skin. Buzz avoids the problem of earwax of conventional hearing aids. It also eliminates the need for an audiologist. At $589, it is considerably cheaper than hearing aids from the “Big Six.”
