The Panasonic RP-HC200E Headphones can cut out a huge 81 of background noise. Not only do they have this but they also deliver high audio quality that can match that of monitor headphones, even when the noise cancelling circuit is off. Audio is often distorted in other noise cancelling headphones when the noise cancelling is turned off but this doesnt happen with the RP-HC200Es. Music doesnt have to be turned up loud as you dont have to overcome the interference of outside noise. The soft and cushioned ear pads also make these headphones very comfortable. This means you can wear the RP-HC200E Headphones from Panasonic for long periods of time without them becoming uncomfortable.
