Denon AH-NC732 Active Noise Cancelling Headphone

The Denon AH-NC732K Active Noise Canceling Headphone is a compact pair of headphones that can effectively reduce low frequency noise like engine noise, up to 95%. They are quite compact, have a lightweight collapsing design and are comfortable on your ears. They come in a small molded carry case that can be easily slipped into a carry bag while traveling. The headphone case also has enough space to contain other adaptors and cables. They are iPhones/Touch compatible with no adaptor needed. With a single AAA battery, they can get up to 40 hours of battery life.

They do not just fit around the ears, but cover the entire ear like a seal so as to get the maximum noise reduction. They are quite comfortable to wear. However, it may take a while to find a perfect fit.

Many people will use them for the noise cancellation feature rather than playing music through them. There is a small switch at the side of the headphones that can be used to turn the noise cancellation on and off. With this switch turned off, the humming of airplane engines and other noises inside an airplane can be clearly heard. When the switch is turned on, the noises reduce by a tremendous amount. The sound of the airplane engine and other noises would be feebly audible as if from a great distance.

The effect of listening to music the first time on them is not as impressive as compared to their noise reduction capabilities. Fresh out of the box, these headphones may not sound as good as a well-used pair. They may sound bright or harsh and you may be disappointed with the sound coming out of them. With the noise cancellation switch off, the effect could even be worse. ‘Burn in’ or ‘break in’ may be required to make them sound the way they are intended. You can play music continuously and loudly through them for a few hours to burn in your new pair of headphones. They begin to sound better, smoother and relaxed, once that is done. However, these still fall below the standards of other common headphones.

Check the EQ settings on the player to find the one best suited for you. The volume adjustments are different when compared to other common headphones in that these have to be raised to about 90% to get the kind of sound that the others gave at a middle setting.

They are quite convenient for use with their detachable cords and the case. They are good value for money if they can be purchased at a local dealer with ample discount.
