This hysteresis, so that the diaphragm can not be received with the music signal stand, the result becomes vague blur, the details disappear or twist area. Reduce the impact of the hysteresis on the music, it is necessary to improve the current conversion efficiency and charge and discharge speed, improve the ability to instantly output large current, to strengthen the control of the diaphragm to improve the control of the headset, headphones to achieve the best status!\u003c\/p\u003e\n\u003cp\u003e   \u003c\/p\u003e\n\u003cp\u003e Specifications:\u003c\/p\u003e\n\u003cp\u003e 1.
