Note AKG did a fine tune on the driver – they covered all the 4 holes on the back cup and only leave the central hole open.

DIY suggestions 

We highly recommend using this driver with our genuine wood headphone kit model B5 and B9 to 100% reproduce original sound. 



Note: the dynamic drivers have been paired to ensure sound and quality fully balanced between right and left channels. Therefore we don’t offer single unit.  

Soldering: overheated (>250 degree C) soldering iron or overtime soldering (>2s) may permanently damage the driver. Please managed down both in your DIY. 

  • Installation: the driver has Sintered NdFeB Magnetic inside with extremely strong attraction power. Damage may caused by attracting anything hitting the fragile diaphragm. 
  • Others: applying high-voltage, storing in high temperature/humidity environment… all may cause unrecoverable damage.
