Learn how to set up and connect your Grado 4-Conductor Extension Cable for X Series headphones. Step-by-step instructions with common mistakes to avoid.

Quick Answer

Connect the 1/4-inch plug of the Grado 4-Conductor Extension Cable into your X Series headphone jack, then plug your audio source into the cable's jack. For longer runs, piggyback up to three cables without signal loss.

Why Use a 4-Conductor Extension Cable

The Grado 4-Conductor Extension Cable uses the same super annealed copper wire as the X Series headphone cables, so you get the same sound quality even when moving farther from your source. The braided sheathing adds durability and reduces tangles.

Piggybacking Limitations

You can connect up to three extension cables in series for longer reach. Grado guarantees no degradation of sonic quality when using their cables with Grado headphones, but stacking more than three may introduce strain on the connectors.

Setup Steps

Step 1: Identify the connectors: Locate the 1/4-inch (6.3mm) plug (male end) and the 1/4-inch (6.3mm) jack (female end) on the extension cable. The plug goes into your headphone, the jack receives the source cable. Do not force the plug into a mini-jack source without an adapter.
Step 2: Connect the extension to your headphones: Insert the 1/4-inch plug firmly into the jack on your Grado X Series headphones. Twist slightly to ensure a snug fit—loose connections cause intermittent audio. If the plug feels loose, check for debris in the headphone jack.
Step 3: Connect your audio source: Plug your audio cable (from an amplifier, DAC, or player) into the extension cable's 1/4-inch jack. Ensure both connections are fully seated before turning on the audio. A partially inserted plug can cause channel imbalance or static.
Step 4: Piggyback for longer distances (optional): To extend further, connect the jack of the first extension cable to the plug of a second Grado 4-Conductor Extension Cable. Repeat up to three cables total. Grado guarantees no sonic degradation within this limit. Do not exceed three cables—connector strain may affect reliability.
Step 5: Route the cable to avoid stress: Lay the cable so it is not pulled taut or bent sharply at the connectors. Use cable clips or gentle loops to manage slack. Avoid stepping on or rolling chairs over the cable. Sharp bends near the plug can damage internal wires over time.
