Learn how to use the Grado 12-Conductor Mini Adaptor Cable for X Series headphones. Step-by-step guide to connect, protect, and get the best sound from your setup.
Quick answer
The Grado 12-Conductor Mini Adaptor Cable lets you connect X Series headphones with a 1/4 inch plug to devices that use a 1/8 inch jack, while protecting the headphone's output circuit board.
Why use the 12-Conductor Mini Adaptor Cable?
The Grado 12-Conductor Mini Adaptor Cable is designed specifically for X Series headphones. It converts a 1/4 inch (6.3mm) plug to a 1/8 inch (3.5mm) plug, but unlike a simple adapter, it includes 8 inches (20cm) of cable. This extra length eliminates the added leverage that a bulky adapter would place on the output circuit board of your source device.
Using the mini adaptor cable instead of a rigid plug adapter helps prevent stress on the headphone jack and the internal components of your audio player, phone, or amplifier. This is especially important if you frequently switch between devices with different jack sizes.
What to check before connecting
Make sure your Grado X Series headphones have a 1/4 inch plug. The 12-Conductor Mini Adaptor Cable is built with the same super annealed copper wire used in the headphone cable, so it maintains signal quality. If your headphones are from an older series or use a different connector, this cable may not fit.
Also confirm that your source device has a standard 1/8 inch (3.5mm) jack. Some portable amplifiers or audio interfaces use a 1/4 inch jack, in which case you would not need this adaptor cable.
How to use the Grado 12-Conductor Mini Adaptor Cable
- Connect the adaptor cable to your headphones: Plug the 1/4 inch (6.3mm) jack of the mini adaptor cable firmly into the headphone cable's 1/4 inch plug. Make sure the connection is fully seated to avoid intermittent audio or static. A loose connection can cause crackling or one-sided audio. Always push the plug in until you feel it click or stop.
- Connect the adaptor cable to your source device: Insert the 1/8 inch (3.5mm) plug of the adaptor cable into the headphone jack of your phone, laptop, or portable player. Do not force it; if it does not go in smoothly, check that the plug matches the jack size. Forcing a plug into the wrong size jack can damage both the cable and the device port.
- Route the cable to avoid strain: Let the 8-inch cable hang freely or drape it gently so it does not pull on the headphone jack. Avoid bending the cable sharply near the connectors, as repeated stress can weaken the wire over time. Bending the cable right at the plug is a common cause of connection failure. Use gentle curves instead.
- Test audio and adjust volume: Play a familiar track and listen for clarity, balance, and any distortion. Start with low volume and increase gradually. If you hear static or one channel drops out, check both connections. Distortion or imbalance usually means a poor connection, not a problem with the headphones themselves.
