The noise-canceling headphones are best suited to eliminate unwanted noise in such situations.
Most products use active noise suppression method of noise cancellation. The headphones have a small amplifier that produces a low pressure second sound waveto the higher ones of the noise and cancel them out thereby reducing the noise considerably. The destructive interference of sound cancels out any noise that may disturb the listener.
Usually, the noise isolation headphones reduce the lower frequency portions of the noise. To reduce the higher frequency portions these music headphones rely on the ear cups.
At times one may notice slight hiss sound in these noise cancellation headsets. This nose is not due to the fact that noise cancellation earbuds are spoilt, it's just that the waveform that they have produced to cancel the noise is not an exact match.

In fact, if you put on these noise cancellation headphones in a loud environment, you will feel an eerie silence. Most noise cancellation products need to use AAA power batteries. They can not work without a power source, and some are rechargeable.
Noise cancellation headphones have some limitations also. They respond extremely well to continuous source of noise and do not work as well with just occasional sources of loud noises. Noise cancellation headphones are little more bulky then the normal ones as they carry extra circuitry. Sometimes, unwanted signals say from mobile phones are converted to sounds by noise cancellation headphones. These limitations of noise cancellation headsets vary from one manufacturer to other and are not generic in all those available in the market.
Noise cancellation products by Bose and Sony are most popular. Bose noise cancellation headphones are little more expensive then ones marketed by Sony. Noise reduction units are available in all three styles in the market, the in ear style, over the ear style and around the ear style.
While using noise cancellation headphones one must be prepared for more power usage then normal units In few instances, these headphones may distort the audio signals like music that you are listening to, these are mostly the lower cost versions that have fewer features.

The best versions are made of light-weight materials and are extremely comfortable to wear for longer periods of time.
As always, If are driving on the road, it is not advisable to use any new technology headsets as listening to sound signals behind you and around you may be important. With noise cancellation earbuds, one need not pull the volume higher then required, in fact these models allow you to have the volume much lower than normal sets.
