DIY suggestions (Sound fine tune)

Headphone drivers need to be fine tuned based on the acoustic structure of the headphone shells, etc. Normally it requires special expertise and professional instruments.

Grado headphone shell is fully open and makes the tuning very easy and straightforward. Simply cover the 2 holes as shown below you will get 100% PS1000e sound reproduced! Note you may use double-sided tapes or other tapes. The key is fully blocking the air flow. And if you prefer more bass or highs than original, you can unblock or block 1 more hole.

We highly recommend using this driver with our PS1000e or GS3000e DIY kit to 100% reproduce the 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.
