Digital Signal Processing (DSP) improves the sound quality though analytical processing of the original signal. DSP tweaks performance in 5 ways：
– Generates wider frequency output
– Filters out any reverberation
– Automatic gain control
– Dynamic adjustment
– Real-time channel mixer
DSP is able to achieve a higher quality of music than the original input. By the end of the audio reconstruction, the earphones give balanced and flawless sound, which can be described as breathtaking.
Active Noise Canceling (ANC) works to give you the illusion of a quieter environment by detecting outside noise with a microphone and then adding a negative sound to counteract the outside noise. With ANC you don’t need to crank up the volume just to hear your music. Sound is detected and sent to noise cancellation circuitry. And then an inverted ANC wave cancels ambient sound out.
Passive noise canceling is another type, where the noise is reduced by physical blocking, this is like having a pair of earmuffs on your ears. Compared to passive noise canceling, good ANC can not only muffle but almost completely eliminate certain frequencies from 20Hz to 20 KHz.Another advantage of ANC headphone is the effect is controllable. You can control the ANC function and turn it off when you need to talk to your friend or teammate.
