The demand for noise canceling headphones is now expanding due to more people using public transportation, especially long flights where noise canceling headphones reprieve listeners from noisy surroundings. The Panasonic RP-HC200-W offers a high noise canceling effect of 81%. It also delivers quality sound equal to that of monitor headphones and is capable of reproducing high quality sound even when the noise canceling circuit is off. With some conventional noise canceling headphones, sound quality often deteriorates when the circuit is off. With RP-HC200-W, you can also switch off the circuit when noise canceling isn't required.
