Panasonic RP-HC700 Noise-Canceling Headphones
Today I want to introduce a Noise-Canceling Headphones from Panasonic called RP-HC700, known as reduced by 95% environmental noise.
Most of the conventional active noise-canceling headphones design to reduce the engine noise, rarely for reducing the general environmental noise. With the CSR announced a new generation of chips, the main noise-canceling headphones are also making a great leap forward, including this RP-HC700. The principle of such active noise-canceling headphones, through several small microphone to collect ambient noise, and then offset the noise from the chip to produce a reverse sound wave; so the noise-cancelling function will not work without battery, but will not affect the normal music player.
This headphones only use 40 mm single, sound frequency range of 10Hz ~ 30KHz, using a AAA battery can be maintained under the 15 hours of noise reduction capabilities, and you will have two colors black and white color choice.
