The active noise reduction of the bhi NCH headphones allows a very relaxed listening, even if it is loud all around. Delivery includes cable and 1x AAA battery.
No matter if you want to reduce noise in the aircraft cabin, air conditioning noise, train noise, background noise and similar types of continuous ambient noise - the bhi NCH provides a much improved listening experience. The adjustable headband and soft over-ear cushions ensure that the headphones fit comfortably. The NCH headphones require one AAA alkaline battery (included). Active noise cancelling can easily be switched on and off with the switch, and a green LED indicates the operating status.
The bhi NCH headphones do not work like our other DSP products with noise cancellation, but use Active Noise Cancellation Technology (ANC) to reduce distracting background noise, creating a comfortable and relaxing listening environment in areas with high ambient noise. The NCH noise-canceling headphones feature a miniature microphone in the earpiece to pick up ambient noise (such as traffic noise and aircraft cabin noise). The electronics in the earphones invert the ambient noise 180° out of phase with the external ambient noise. This suppresses the disturbing ambient noise without affecting the sound you are listening to, resulting in a significantly improved listening experience.
