[0042] The present disclosure also provides a headset acoustic performance testing device, including the headset acoustic performance testing device 10 described in any of the above embodiments, the headset acoustic performance testing device also includes a Bluetooth adapter, an amplifier and sound card integrated machine acquisition system and an acoustic testing system.
