A hearable is an ear-worn, always-on, intelligent consumer electronics device. Designed to be unobtrusive, enable face-to-face communication, and integrate easily into daily life, these smart earbuds often include self-fitting technology to ensure performance is matched to individual ears. In addition to being used as a personal sound amplification device for people with mild to moderate hearing loss, hearables can help protect your hearing thanks to active noise cancellation functions. They also have other applications including audio-based information services, health monitoring, in-ear detection, heart rate monitoring, and many others. This new generation of smart devices relies on and works in conjunction with voice-enabled virtual assistants that provide real-time responses or can access other apps. Added hardware like motion, proximity, heat and light sensors as well as skin detectors or other biometric interfaces can be included to gather information about the environment, location, and the wearer’s current state, activities, and even mood.

Earbuds and headsets (TWS)

Headsets come in a wide variety of form factors and functionality.  The primary function of a headset is to deliver high quality stereo music and sound, but the most advanced headsets incorporate a number of other functions including microphones for
