The active noise reduction of the NCH bhi headphones allows for a very relaxed listening, even if it is loud all around. Delivery includes cable and 1 AAA battery.
No matter if you want to reduce noise in the plane cabin, air conditioning noise, train noise, background noise and similar types of continuous ambient noise - the bhi NCH provides a much better listening experience. The adjustable headband and soft ear pads ensure the headphones fit comfortably. NCH headphones require an AAA alkal battery (included). Active noise cancellation can be easily switched off with the switch and a green LED indicates the operating status.
NCH bhi headphones don't work like our other noise-cancelling DSP products, but they 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-cancelling headphones are equipped with a miniature microphone in the headset to collect ambient noise (such as traffic noise and airplane cabin noise). The electronics in the earbuds reverse ambient noise at 180 degrees out of phase with external ambient noise. This suppresses the disturbing ambient noise without affecting the sound you are listening to, resulting in a greatly improved listening experience.
