With the development of smart phones, the cancellation of the 3.5 headphone jack has become a trend. A large number of existing wired headset equipment is facing scrap, which wastes resources. Bluetooth connection equipment allows old equipment headsets to easily connect to Bluetooth devices such as mobile phones. It has longer standby power than existing Bluetooth headsets, and is more convenient to use. It rejuvenates old equipment and reduces unnecessary electronic equipment pollution and waste.
