                     Pao headphones:

As we all know, new cars, machines, and so on, in normal use is to go through a program called "break-in" phase, so that the internal mechanism of full coordination and cooperation, advance to the in the Groove. Likewise, the push unit of the headset (headset speakers) is a mechanical device that technically should be a combination of semi machinery, electronic, so headphones would have to go through "break-in" will be more perfect. New headphones are relatively shallow dive sounds are low frequency, volume is also small, blunt, if performance is not soft enough, symptoms such as high frequency there are glitches, too sharp (of course, this is decided by the quality of the headset itself). Praise after a period of time, sound full ease, sound quality is better.

So, how do you praise headphones? Useful special frequency generator to generate a fixed frequency or scanned, and then the headphone praised this way, this method is quite obvious, can also shorten the time used by many. But most of players are no this category of instrument; in computer development changing of today, many of enthusiasts series out has some program, using computer processing out some waveform, and frequency, through sound card output, reached some real frequency occurred instrument of effect, this is so-called of "virtual instrument" praised machine; yiqian also pop a is simple of method, is directly received Shang radio, adjustable to a no radio of frequency Shang, using radio issued of "SI SI" sound (pink noise) long time let headphones work, To achieve the effect of praise. But less obvious with this method, you might as well put on headphones to listen to music directly sooner. Following on introduced about side heard side praised of method: using test dish with 30%-40% of volume continuous play 12-24 hours, rest day then has select of continuous play different style of CD dish 5-10 hours (including vocals, and symphonic, and electronic Le, and pop and AV site), next select you most like of CD with larger of volume (you can accept of maximum sound pressure, note volume not can had big, otherwise may on headphones caused damaged) play 1-2 hours, Final recovery medium volume plays soft music (like bandari and piano) for 5 hours, at this point, congratulations, Pao process basically completed.
