As shown is an active noise rejection stereo headset. It owns an exceptional active noise cancellation performance at low frequencies compared to feed-forward designs. It significantly reduces the occlusion effect, common with tradition in-ear earphone design.

• Up to 20dB Noise Cancellation(peak), and up to 3kHz active noise cancellation bandwidth
• Feedback Active Noise Rejection design
• With appropriate earphone grommet, 15dB total noise cancellation from 50Hz to 10kHz is possible
