Contents: NCH noise cancelling headphones, 1 x AAA alkaline battery.
The bhi NCH active noise cancelling headphones (ANC) do not work like our other DSP noise cancelling products but effectively reduce external ambient background noise enabling you to concentrate more and enjoy your listening experience when listening in a noisy environment. The over-ear style NCH headphones also give good passive audio isolation from external noise.
Using Your Headphones
They are an excellent choice for those wanting to reduce aircraft cabin noise, air conditioning noise, train noise, ambient background noise and similar types of continuous environmental noise so that they can enjoy a much improved listening experience. They are especially good to use on a train or airplane whilst listening to audio or watching a video. The adjustable headband and soft over-ear pads make sure that the headphones are a comfortable fit. The NCH headphones require one AAA alkaline battery (supplied) and the active noise cancellation can be easily switched on and off with the simple switch, and a green LED indicates whether it is active or not. If your headphone socket is 1/4" (6.35mm) then you will need to use an audio adapter like our ADP-P007 (not supplied)
Active Noise Cancellation
The bhi NCH headphones do not work like our other DSP noise cancelling products but use active noise-cancelling technology (ANC) to reduce distracting background noise, providing a comfortable and restful listening environment in areas with high ambient noise. The NCH noise-cancelling headphones feature a miniature microphone in the earpiece that picks up ambient noise (like traffic noise and aircraft cabin noise). The electronics in the ear piece invert the ambient noise by 180° out of phase with the external ambient noise. This has the effect of cancelling out the annoying ambient noise without diminishing the audio you are listening to, resulting in much improved listening experience.
