2. Selecting and Installing Ear Tips

The correct ear tips are crucial for sound quality and comfort. Experiment with the included ear tips to find the best fit for your ears.

• Gently remove the pre-installed ear tips by pulling them off the nozzle.
• Select a pair of ear tips that provide a comfortable and secure seal in your ear canal.
• Push the new ear tip onto the earphone nozzle until it is firmly attached.

3. Wearing the Earphones

The DX1 earphones are designed for an over-ear fit to ensure stability and comfort.

1. Identify the left and right earphone units.
2. Place the earphone unit into your ear canal.
3. Guide the cable over the top and behind your ear. The cable is designed to conform to the shape of your ear for a secure fit.
4. Adjust the earphone and cable until a comfortable and stable fit is achieved, ensuring a good seal in the ear canal.

Operation

Connecting to Audio Devices

The LETSHUOER DX1 earphones feature a 3.5mm connector for wide compatibility.

• Insert the 3.5mm plug of the earphone cable into the headphone jack of your audio source (e.g., smartphone, digital audio player, computer, gaming console).
• Ensure the plug is fully inserted for optimal sound.
• Adjust the volume on your audio device to a comfortable listening level before placing the earphones in your ears.

Compatible devices include: Laptops, Desktops, Gaming Consoles, Tablets, Telephones, Smart Speakers, Televisions, Music Production Equipment, Car Audio Systems, and Cellphones.

Maintenance

Cleaning the Earphones

• Earphone Units: Use a soft, dry, lint-free cloth to wipe the stainless-steel shells. Avoid using harsh chemicals or abrasive materials.
• Ear Tips: Remove ear tips from the earphones. They can be gently washed with mild soap and water. Ensure they are completely dry before reattaching.
• Nozzles: Carefully remove any earwax or debris from the earphone nozzles using a small, soft brush or a specialized cleaning tool. Be gentle to avoid damaging the driver mesh.

Cable Care

• Avoid sharp bends or excessive pulling on the cable.
• When storing, coil the cable loosely to prevent tangling and damage.
• If the cable becomes dirty, wipe it with a soft, slightly damp cloth.

Storage

When not in use, store your DX1 earphones in the provided storage case to protect them from dust, moisture, and physical damage.

Troubleshooting

• No Sound or Intermittent Sound:
  • Ensure the 3.5mm plug is fully inserted into the audio source.
  • Check that the detachable cable connectors are securely attached to the earphone units.
  • Verify the audio source is playing and its volume is turned up.
  • Test with a different audio source or cable if possible.
• Poor Sound Quality (e.g., lack of bass, tinny sound):
  • Ensure ear tips provide a proper seal in your ear canal. Try different sizes or types of ear tips.
  • Check for any obstructions in the earphone nozzles.
  • Ensure the cable connections are secure.
• Driver Flex / Crinkling Sound:
  • Some in-ear monitors may exhibit a slight "crinkling" sound or sensation when inserted or adjusted due to air pressure changes. This is often a characteristic of the design and not necessarily a defect.
  • Try inserting the earphones slowly and gently to minimize this effect.
  • Ensure the ear tips are not creating an overly tight seal that traps air.
• Discomfort:
  • Experiment with different ear tip sizes and materials to find the most comfortable fit.
  • Ensure the earphones are correctly positioned in your ears with the cable routed over the ear.
