1. Locate the single-side, detachable flat elastomer cable provided with your headphones.
2. Identify the connector end of the cable designed for the headphone earcup.
3. Insert the cable connector into the port on the left earcup of the JBL J55 headphones.
4. Twist the connector clockwise to engage the cable-locking mechanism, securing the cable firmly in place.
5. Connect the 1/8" (3.5mm) gold-plated jack at the other end of the cable into your audio source (e.g., smartphone, tablet, computer). The extension ring on the jack ensures compatibility with most smartphone cases.

2.2 Wearing the Headphones

• Gently extend the headband to fit comfortably over your head.

3. Operating the Headphones

3.1 Listening to Audio

Once connected to your audio source, begin playing your desired audio. The JBL J55 headphones feature premium, high-performance JBL drivers designed to deliver precise, powerful sound with pure, deep, and accurately produced bass.

3.2 Using the DJ Pivot Mechanism

The J55 headphones incorporate a unique 180-degree DJ pivot mechanism. This feature allows you to rotate either earcup upwards while wearing the headphones. This is useful for situations where you need to hear external sounds or engage in conversations without removing the headphones entirely.

• To activate, gently rotate one of the earcups up to 180 degrees.
• To return to standard listening, rotate the earcup back into its original position.

3.3 Portability and Storage

For easy storage and transport, the earcups can rotate inwards under the headband, allowing the headphones to lay flat. This compact design, combined with the included padded carry pouch, protects your headphones when you are on the go.

4. Maintenance

4.1 Cleaning Your Headphones

• Use a soft, dry cloth to wipe down the exterior surfaces of the earcups and headband.
• For the soft leather ear cushions, a slightly damp cloth can be used, but ensure they are completely dry before storage. Avoid using harsh chemicals or abrasive cleaners.
• Periodically check the cable and connectors for any dust or debris and clean gently if necessary.

4.2 Cable Care

The J55 features a tangle-resistant, flat elastomer cable. To prolong its life:

• Always disconnect the cable by pulling on the plug, not the cable itself.
• Avoid sharp bends or kinks in the cable.
• When not in use, store the detachable cable neatly, preferably coiled loosely.

4.3 Storage

Always store your JBL J55 headphones in the included padded carry pouch when not in use. This protects them from dust, scratches, and minor impacts, ensuring their longevity and maintaining their appearance.

5. Troubleshooting

5.1 No Sound or Intermittent Audio

• Check Cable Connection: Ensure the detachable cable is securely connected to both the headphone earcup (with the twist-lock mechanism engaged) and the audio source.
• Verify Audio Source: Make sure your audio source (e.g., smartphone, computer) is playing audio and its volume is turned up. Test with another audio source if possible.
• Inspect Cable: Check the audio cable for any visible damage or kinks. If damaged, consider replacing the cable.

5.2 Poor Sound Quality

• Proper Fit: Ensure the headphones are worn correctly and the ear cushions form a good seal around your ears. An improper fit can lead to reduced bass or overall sound quality.
• Audio Source Quality: The quality of your audio files or streaming service can affect sound. Try playing high-quality audio files.
• Clean Connectors: Ensure the 3.5mm jack and the port on your audio source are clean and free of debris.
