Singers may perceive their own voice as “booming,” leading to misjudgment of pitch and volume. To address this issue, the system is equipped with multiple in-ear EQ presets, effectively reducing the occlusion effect. The result is a clearer, more natural sound that helps you perform with greater confidence on stage.\u003c\/p\u003e\n\u003cp\u003eYou can freely switch between five different in-ear EQ curves to suit various performance environments and personal listening preferences.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003ePhase Inversion\u003c\/h3\u003e\n\u003cp\u003eIn complex stage environments, multiple sound sources or overlapping monitor mixes may cause phase cancellation, leading to low-frequency loss or excessive buildup in certain ranges.
