Many people who have succumbed to the temptation of noise canceling headphones can give an opinion about how effective the noise-reduction technologies can be: suffice to say some are more effective than others. But one thing the majority of users seem to agree on: as far as audio quality goes, noise-canceling headphones usually aren’t anything special, and sometimes they’re downright terrible.

JVC aims to change that with its new top-of-the-line HA-NC250 noise-canceling headphones. The new cans combine noise-canceling and isolation technology with what JVC promises is outstanding sound quality in order to provide an outstanding listening experience.

Noise-canceling technology uses a built-in microphone that detects environmental noise from low-frequency sources (20-1500hz), such as jet engines, leaf blowers, subway trains, server fans, and household appliances. Sony engineers have improved a noise canceling circuit that creates an equal an opposite sound wave to cancel such noise, creating a better environment for listening to in-flight movies or portable audio devices. For example, Sony tests indicate that the MDR-NC50 headphones offer a 14db reduction of sounds at the 300hz level.

Using 40 mm drivers and neodymium magnets in combination with its noise cancellation circuitry, the MDR-NC50 headphones provide the audio quality and clarity of a home listening headphone – even when they’re used far from home.
