Air conditioning is gone.The train whistled.The plane engine is gone.The vehicles on the highway became a well-behaved sheep.
Before the first note hits the eardrum, this quiet is enough to arouse your suspicion that you have never had anything around the world.
I can have such an experience, just because I was wearing a noise cancelling headset - COWIN HE8.
Because of work, I often take the flight, high-speed rail raid in the vicinity, accompanied by the ubiquitous at the end of noise everywhere. A moment of peace has become a luxury.
Cowin HE8 is an active noise cancelling headphone. It is based on the two sides of the microphone to collect the external noise, issued the same frequency intensity, the opposite phase of the sound waves, superposition offset. Of course, you do not expect it to be able to shield off the neighbor's child's screams.
Work, get off work, overtime, as well as the anger of the boss , finally the end of the day but also troubled by the messy trivial . You want to find the world's mute button, press hard to see them claws but not a little bit of sound.
But I advise you still do not wear COWIN HE8, do not connect any equipment to shield the world. Because it will make everything around to become distant and unfamiliar.
This time,it's just fine to point music.
Now, as long as $ 79.99, give your world a key to mute.
