Fit

Twist to Lock: For a snug fit, place the GT220 vertically in your ear and twist backwards until they are locked in.

Note: While a tight seal of the silicon in your ear is important to great sound, we recommend to use a fit that’s comfortable. If placing the GT220 in your ear without twisting feels best, then you’re all ready done.

Support

Trouble Connecting?

When your device pairs with the GT220, it connects to one side that then talks to the other side (e.g. the device pairs to Left, Left talks to Right).

If your device loses connection to the initially paired side, it will try to connect to the other. In this case, two ‘Grado GT220’ may appear in your Bluetooth list. In most cases this does not change any usage. In the rare case your phone has trouble pairing if this happens, simply forget one of the GT220. If it persists, forget both ‘Grado GT220’ and pair again.

Factory Reset:

When placed in their charging case, the GT220 will start to charge and disconnect from your device. At this point, tap either the L or R headphones 3 times. The GT220 may flash and turn off & on multiple times during reset.
