• Personalized feedback: The real-time feedback on movement speed allows users to optimize their exercise routines and make adjustments as needed.

Abstract

A control system includes earphones including a housing having a space therein and an air-permeable path from one end of an ear canal of a user to one end of the ambient environment, and an opening and closing valve accommodated in the housing and capable of blocking a part of the path, the earphones being worn on left and right ears of the user, respectively, and a wireless terminal carried by the user. The wireless terminal transmits a signal indicating that the moving speed is a speed within the predetermined range to the earphones when determining that a moving speed of the user is within a predetermined range. The earphones control the opening and closing valve based on the signal acquired from the wireless terminal.
