Relaxing silence or musical enjoyment - just as you like!
The ContraNoise headphones from Bennett & Ross with their active noise cancelling function ensure absolute silence despite loud ambient noise. Those who find this too quiet can simply connect their smartphone or tablet to the headphones to listen to music or make a call. Whether by cable or via Bluetooth - the decision is yours.
Active Noise Cancelling
Great technology: the integrated microphone detects the ambient noise and outputs the sound waves arriving from the external environment out of phase via the headphone speakers. Thus, due to the resulting interference, the external sound is reduced by up to 25 dB. This technology creates relaxing moments of peace and quiet on the plane, in the train or at work.
Bluetooth connection with hands-free function
Independent of the noise cancelling function, the ContraNoise can, of course, also be used as a normal headphone. All kinds of devices such as smartphones or tablets can be connected via Bluetooth. Volume and track selection can be controlled from the player or directly from the ContraNoise. The ANC-250BK also has a hands-free function that allows incoming calls to be answered and made directly. Of course, the music pauses during the call and then automatically resumes playback.
Travel Case and accessories
The foldable headphones come in a light and sturdy case including charging and AUX cable. The integrated Li-Ion battery has enough power for approx. 10 hours of talk time or 5 hours of music playback. Should the battery be used up, the ContraNoise can be used as normal passive headphones with its 1.6m long AUX cable.
Now, it's finally quiet!
