Dear customer
Thank you for purchasing this product. For optimum performance and safety, please read these instructions carefully.

The noise canceling function
Environmental noises in airplanes, trains, and buses, and noise caused by air-conditioners is reduced by a third, providing a quieter listening environment. This function allows you to enjoy music without raising the volume too high, and is, therefore, kinder to your ears. This unit mainly reduces the annoying low frequency sounds below 1500 Hz. For this reason, sounds with higher frequency portions, from car horns, telephones and human voices, remain relatively intact.
