Setup
1. Attaching the Cables
- Identify the left and right earpieces and cable connectors. The earpieces are marked 'L' and 'R'.
- Align the cable connector with the corresponding socket on the earpiece. Ensure the connector is oriented correctly.
- Push the connector firmly into the socket until it clicks into place. Do not force the connection.
- To detach, grasp the cable connector firmly and pull straight out from the earpiece. Avoid pulling on the cable itself.
2. Choosing and Installing Eartips
Proper eartip selection is crucial for sound quality and noise isolation. Experiment with the included Comply memory foam and silicone eartips to find the best fit for your ears.
- Silicone Eartips: Select a size that creates a comfortable, snug seal in your ear canal.
- Comply Memory Foam Eartips: Compress the foam tip by rolling it between your fingers before inserting it into your ear. Hold it in place for a few seconds while the foam expands to create a custom seal.
3. Wearing the Monitors
- Insert the earpieces into your ears, ensuring a secure and comfortable fit.
- Guide the memory wire portion of the cable over the top of your ear. Gently bend the memory wire to conform to the shape of your ear for added stability.
- Adjust the cable length using the cable cinch to prevent tangling and provide a secure fit behind your head or under your chin.
Operating Instructions
1. Connecting to an Audio Source
Connect the 3.5mm audio jack of the chosen cable to your audio device (e.g., smartphone, tablet, mixer, audio interface). If your device requires a larger connection, use the included 1/4" (6.3mm) adapter.
2. Using the Headset Cable (with Microphone and Remote)
The headset cable allows for hands-free calling and media control with compatible smartphones and tablets.
- Microphone: Position the microphone close to your mouth for clear voice pickup during calls.
- Remote Button: Functions may vary by device, but typically include:
- Press once: Play/Pause music, Answer/End call
- Press twice: Skip to next track
- Press three times: Go to previous track
Maintenance
1. Cleaning
- Regularly clean the eartips with a soft, damp cloth. Remove eartips from the monitors for thorough cleaning if necessary.
- Wipe the earpieces and cables with a dry, soft cloth to remove any sweat or debris. Avoid using harsh chemicals or abrasive materials.
- Ensure the earpieces are dry before reattaching eartips and storing.
2. Cable Care
Handle the detachable cables with care. Avoid sharp bends, excessive pulling, or twisting, which can damage the internal wiring.
3. Storage
When not in use, store your MX4 PRO monitors and accessories in the provided protective carrying case. This helps prevent damage from impacts, dust, and tangling.
