4. Setup and Wearing

4.1 Connecting the Cable

1. Identify the left (L) and right (R) earphone units and cable connectors. The cable connectors are typically marked.
2. Align the 2-pin connector on the cable with the corresponding socket on the earphone unit. Ensure the pins are correctly oriented.
3. Gently push the connector into the socket until it is firmly seated. Do not force the connection.
4. Repeat for the other earphone unit.

4.2 Choosing and Attaching Ear Tips

Selecting the correct ear tips is crucial for sound quality and comfort. Experiment with different sizes and materials (silicone or foam) to find the best fit. A good seal ensures optimal bass response and passive noise isolation.

1. Gently remove the pre-installed ear tips by pulling them off the nozzle.
2. Select a desired ear tip size and material.
3. Push the new ear tip onto the earphone nozzle, ensuring it is securely attached and forms a tight seal around the nozzle.

4.3 Wearing the Earphones

The TRN Conch features an ear-hook design for stable and comfortable wearing.

1. Insert the earphone unit into your ear canal.
2. Guide the cable over the top of your ear, allowing the pre-formed ear-hook section to rest securely behind your ear.
3. Adjust the earphone and cable for a snug and comfortable fit.

5. Operating Instructions

5.1 Basic Audio Playback

Once connected to your audio source (e.g., smartphone, digital audio player, computer) via the appropriate connector, simply play your desired audio. Adjust the volume on your source device.

5.2 Using Interchangeable Tuning Nozzles

The TRN Conch comes with three interchangeable tuning nozzle filters, allowing you to customize the sound signature to your preference. Each filter has a different internal diameter and net, which affects specific audio frequencies.

1. Gently unscrew the currently installed nozzle filter from the earphone unit.
2. Select a new tuning nozzle filter.
3. Carefully screw the new filter onto the earphone nozzle until it is secure. Do not overtighten.
4. Listen and compare the sound profiles to determine your preferred tuning.

5.3 Swapping Connectors

The cable features swappable connectors for compatibility with various audio devices.

1. Gently pull the currently attached connector (e.g., 3.5mm) from the cable.
2. Align the desired connector (e.g., 2.5mm or 4.4mm) with the cable's connection point.
3. Push the new connector firmly into place until it clicks or feels secure.

6. Tuning Nozzle Filters Explained

The three interchangeable tuning nozzle filters provide distinct sound profiles:

• Reference (Black Sealing Ring): Offers a balanced and neutral sound signature, ideal for critical listening.
• Translucent (Blue Sealing Ring): Provides a slightly brighter sound with enhanced treble, suitable for those who prefer more detail in the high frequencies.
• Atmosphere Enhancement (Red Sealing Ring): Delivers a warmer sound with boosted bass, creating a more immersive and impactful listening experience.

Refer to the included frequency response graph to visualize the impact of each filter on the audio spectrum.

7. Maintenance

7.1 Cleaning the Earphones

• Regularly clean the ear tips and earphone nozzles to prevent wax buildup, which can affect sound quality.
• Remove ear tips and wipe them with a soft, damp cloth. Allow them to dry completely before reattaching.
• Use a small, soft brush or a cleaning tool (if provided) to gently remove any debris from the earphone nozzles.
• Wipe the earphone bodies with a dry, soft cloth. Avoid using harsh chemicals or abrasive materials.

7.2 Cable Care

• Avoid sharp bends or excessive pulling on the cable.
• When storing, coil the cable loosely to prevent tangling and damage.

If you encounter any issues with your TRN Conch In-Ear Monitors, please refer to the following common solutions:

• No Sound or Intermittent Sound:
  • Ensure the cable is securely connected to both the earphones and the audio source.
  • Check the audio source's volume level and ensure it is not muted.
  • Test with a different audio source or cable to rule out device or cable issues.
  • Inspect the 2-pin connectors for any bent or damaged pins.
