To be simple and individual， not expensive， enough for man， what do you think?
Bullet as below picture，QSZ92 9mm， used as the cavity of earphone.
Besides of the new look， high density of the material is the most key point. Voices with less interference since under low vibration to metal.Large space of back cavity， and will be with more air compressed， that makes better elasticity at low frequency， but keeps the high frequency. Bullet of below shows polishing effect and before firing.
Potassium sulfide remains inside of cavity after firing， since close contact with
body every day， and must be removed.
With the help of magnetic polishing machine， surface is neat and clean， but only could finish 10 bullet an hour， makes the earphone more precious.
Shell achieved after polishing both outside and inside， but considering not good visual effect when copper exposed into air， treat with gold plated， including 4 main
procedure as oil removing， activate，nickel plating， gold plating.
Should be under constant temperature，otherwise， will be too dark or too dull.
