Description

This is a pair of Grado Aluminum sleeves with drivers pre-installed. It’s designed to repair or upgrade your low-mid end Grado headphones (e.g., SR60e/80e, Alice) to hi-end series like PS1000e. Instead of plastic sleeves Grado used to use, these sleeves are made of high quality Aluminum and black oxidated, and far more durable. 

How to order 

You can choose from following options:

• Empty sleeve + cover, which you can install with your own drivers
• Sleeve + cover + 44mm Grado drivers, where you can select from low-end (e.g., SR60/80e), mid-end (Hemp, SR225) or high-end (PS1000e) driver pre-installed

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.
