Do you have any recommended suppliers of cups?

While we are finalising our cups and supplier, we recommend to have a look at the “post your grado mods…” thread on Head-fi to get more info on cup makers.

What is the best way to mount the drivers into the cups?

We recommend that the drivers be press-fitted into wooden cups, with the face of the driver flush with the edge of the cup.

What ear pads works best with the drivers?

Our Nhoord Red driver was designed to work best with L-cush type pads, but G-cush type pads can also be used.

What is the recommended burn-in time?

We suggest to use the drivers for about 20 hours at moderate levels, before any critical listening.

How are the drivers shipped?

The drivers are packaged in a heavy card stock box with high density foam placed inside to keep the drivers in place and safe during shipping. We previously used TNT/Fedex to ship but now use a local company that partners with different couriers (DHL, Fedex, Aramex, etc.), depending on what country it goes to. Delivery usually takes about 5 working days.
