Excellent sound quality is essential and noise cancellation is a key to a good headphone.

For example, what is the most impressive noise so loud that you can’t stand? Or, the sound is so harsh that you couldn’t response to any sound in a second or react slower than usual?

People who travel in different cities expose themselves under noisy environment in a long period. Those noises are not just from the planes running but also all kinds of sounds that influence for resting. Moreover, you would hear noises on the way to work, taking metro or buses. These noises not only put you in bad mood but also damage the hearing.

In general, you may block the sound / noises from three aspects, the sound source, way of spreading, and receiving to the ears. The noise generated by the public transportation deserve people’s attention because it usually generates the noise over 85 dB. Whoever stays under such noise level in a long time period will damage hearing. To reduce the noises caused by the public transportation couldn’t be done overnight. Instead of expecting the transformation of public transportation or cutting routes of noise spreading, it’s more practical to solve noise problem through ears receiving.

No matter it’s short or long journey, you always see people wearing headphones in the transportation. In fcat, headphones become most of people’s choice to reduce the ambient noise. Headphones not only help people relieve the pressure but also avoid disturbance by unwanted sound during the journey.

The noise cancellation function of a headphone is divided into two types,  active noise control and passive noise control. The active noise control is to emit a sound wave with inverted phase to the original outer sound through active noise control to effectively cancel each other out – an effect which is called destructive interference. Passive noise control is to surround ears to form a confined space or adopt silicon earplugs to block the outer noises.

Fulicare P103 Headphone adopts Feedback ANC with microphone installed inside of the headphone. Fulicare P103 performs active noise control through complicated patented electronic components and Algorithm. Electronic system detects sounds in most environment ,and then measures, compars, and reacts in real time for microphones emit inverted phase signals to cancel ambient noise. Passive noise control performs noise control through mechanic design of ear muffs and ear cushions and skin friendly materials.

What is hearing care? Fulicare P103 not only performs active noise control but also keeps the sound level without bad effect to health via smart volume cl. Don ’t think good quality sound would always stay the same. No matter how marvelous the sound is, it would be silent as the air if you lost sensitive hearing.
