Production Process
| 1. ear shell selection-->Production ear shell ->Ear shell assembly |
  |
| 2. Cable material selection-->production cable-->cable assembly |
 |
| 3. speaker selection-->production speaker-->speaker assembly |
 |
| Manufacturing technique |
| 1.)ear shell production : |
| ear shell moulding developing -->moulding testing-->ear shell production-->painting,coloring,UV,Electroplating etc-->logo printing-->ear shell assembly |
  |
| 2.)cable production: |
| cable material selection -->cable production-->param string length-->serifing,tinspray painting,wiring-->jack welding-->injection-->testing-->coiling |
 |
| 3.)Speaker production: |
| film,Cone Frame,magnet,circuit board selecting -->magnetizing -->assembling-->stick membrane slice-->gluing-->testing End products assembling : ear shell threading fixed -->speaker welding-->ear shell covering -->sounds quality testing-->cleaning appearance -->packing |
 |
| Testing Methords |
| 1.)Ear shell testing : |
| ear shell moulding testing -->appearance of shell testing-->coloring testing-->logo printing testing-->ear shell assembly testing |
| 2.)Cable testing : |
| cable exterior testing-->cable length testing-->cable welding,wiring testing -->professional testing of positive&negative board electrical -->moulding injection testing-->professional electrical tester testing -->pulling force testing |
 |
| 3.)Speaker testing : |
| positive&negative tester-->sonic scanner-->curve tester |
 |
| 4.)End products testing : |
| threading lenght testing-->cable splice fixed testing-->soldering fixed testing-->covering testing -->pulling force testing-->waving testing-->sonic scanner testing-->curve analyzer testing-->professional audition listening--> exterior testing-->end product testing |
