3. Setup

3.1 Attaching the Cable

The IE 80 S features a detachable cable with a proprietary 2-pin connector. To attach the cable, align the pins on the cable with the corresponding sockets on each earbud. Gently push until you feel a secure connection. Ensure the left (L) and right (R) indicators on the cable and earbuds match.

3.2 Selecting and Fitting Ear Tips

Proper ear tip selection is crucial for optimal sound quality and comfort. The IE 80 S includes various ear tips:

• Silicone Ear Tips: Standard option for a balanced fit.
• Lamella Silicone Ear Tips: Designed for enhanced seal and noise isolation.
• Comply™ Foam Ear Tips: Offer superior comfort and noise isolation by conforming to your ear canal.

Experiment with all three types and different sizes (S, M, L) to find the best fit for your ears. A good seal is essential for rich bass response and effective passive noise reduction.

3.3 Wearing the Earbuds

Insert the earbuds into your ear canals. You may route the cable straight down or over your ears using the included ear hooks for a more secure fit, especially during activity. Adjust the cable length using the slider if present.

3.4 Connecting to an Audio Source

Plug the 3.5mm jack of the earphone cable into the headphone output of your audio device (e.g., smartphone, tablet, music player, laptop). Ensure the connection is firm.

4. Operation

4.1 Adjusting Bass Response

The IE 80 S features a unique manual sound tuning function that allows you to tailor the low-frequency response to your personal preference. Use the included sound adjustment tool to turn the small screw located on each earbud. Turning the screw clockwise generally increases bass, while turning it counter-clockwise decreases it. Adjust both earbuds equally for balanced sound.

4.2 Noise Isolation

With a proper fit, the IE 80 S earbuds provide effective passive noise isolation, reducing ambient sounds and allowing you to focus on your audio. The Comply™ foam ear tips typically offer the best noise isolation.

5. Maintenance

5.1 Cleaning the Earbuds and Ear Tips

Regular cleaning helps maintain hygiene and sound quality. Use the included cleaning tool to gently remove earwax or debris from the ear tips and the earbud nozzles. Ear tips can be carefully removed and cleaned with a mild soap solution and water, then thoroughly dried before reattaching.

5.2 Cable Care

To prolong the life of your detachable cable, avoid sharp bends or excessive pulling. When not in use, coil the cable loosely. The detachable design allows for easy replacement if the cable becomes damaged.

5.3 Storage

Always store your IE 80 S earbuds in the provided carry case when not in use. This protects them from dust, dirt, and physical damage during transport.

6. Troubleshooting

6.1 No Sound or Intermittent Sound

• Ensure the 3.5mm jack is fully inserted into your audio device.
• Check that the detachable cable is securely connected to both earbuds.
• Verify that your audio device's volume is turned up and not muted.
• Test the earbuds with a different audio source or device to rule out device-specific issues.
• Inspect the cable for any visible damage.

6.2 Poor Sound Quality (e.g., weak bass, muffled sound)

• Ensure you have a proper seal with your ear tips. Try different sizes or types (silicone, lamella, Comply™ foam).
• Clean the earbud nozzles and ear tips to remove any obstructions.
• Check the bass adjustment screws on both earbuds to ensure they are set to your desired level and are balanced.
• Ensure the audio source is playing high-quality audio files.

6.3 Uncomfortable Fit

• Experiment with all provided ear tip sizes and materials to find the most comfortable and secure fit.
• Try using the ear hooks for added stability and comfort, especially if the earbuds feel loose.
