88% Noise cancelling technology, highest reduction for canal type earphones
The newly designed RP-HC55 offers the highest noise cancelling for canal type earphones, with a great 88% reduction. These headphones have a compact pen shaped noise cancelling unit that is designed to attenuate low frequency inconsonant noise of 1,500Hz or less, whilst still being able to detect on relatively high frequency components such as automobile horns, telephone rings or the human voice.
