The Edifier Comfo Run air conduction headphones connect to any device that has Bluetooth. They are a suitable choice for running or other athletic activities, as they offer protection against sweat and rain. They are secured with a hook that fits on the outside of the ear, making them more stable during movement. They feature microphone noise reduction, so your callers can hear you clearly.
