In-Ear Detection

Goodix offers a 2-in-1 solution of multi-channel hardware in-ear detection (IED) and touch control with the lowest power consumption in the smallest size among the industry. Such products can be extensively used in all forms of smart earphones such as TWS (True Wireless Stereo), earbuds and headphones. The in-ear detection function allows the headphones to actively detect the wearing status with no physical holes required on the device. The solution allows tap and slide motions on the capacitive button to realize operation on the device, providing users with smarter and more convenient human-computer interactions.
