A specially designed circuit switch is on the phone. It is for clearing up waves of miscellaneous signals.
All use quartz crystal oscillating circuits, so the frequency is very steady.
With audio compressing-expanding technology, the machine can lower noises and increase the dynamic range. It can also lower reecho.
Particular noise detect to avoid interference from outside open the mute system. Choose excellent chipset and high quality component, so that its timbre is very good.
