耳机连接手机后，您可以通过在终端设备直接调节音量大小，也可以在Nothing X app CONTROLS 中设置耳机的"DOUBLE TAP & HOLD"或充电盒Smart Dial的"ROTATE"的手势进行耳机音量的控制：
**Double tap & hold for 1 second, adjust the volume (after triggering and in Double tap & hold state, the volume changes by one bar every 0.9S, and stops rising when the hold control is released)
