The Titan X features a 10mm dual-magnetic, dual-cavity dynamic driver. This design ensures powerful, clean bass and clear, detailed sound reproduction across the frequency spectrum, making it suitable for various music genres and gaming.

3.2 Hybrid Diaphragm
Incorporating a hybrid diaphragm, the Titan X blends a high-rigidity dome with a flexible suspension. This combination delivers crystal-clear details and deep bass, contributing to a balanced and natural sound profile.

3.3 High-Purity OCC Silver-Plated Cable
The earphones come with a 4-strand, high-purity silver-plated OCC copper cable. This Litz construction cable is designed to minimize signal loss and reduce crosstalk, ensuring cleaner sound and enhanced durability. The 0.78mm 2-pin detachable design allows for easy cable replacement or upgrades.

3.4 High-Density Alloy Casing
The Titan X features a high-density alloy housing with a gunmetal gray finish. This robust construction provides durability, scratch resistance, and sweat resistance, maintaining a premium look and feel over time.

3.5 Optimized Sound Signature
Tuned to a modified Harman curve, the Titan X offers a slightly boosted sub-bass for deep lows, clear and forward mids for vocals, and extended treble up to 40kHz for airy details. This tuning provides an engaging and fatigue-free listening experience for various audio content.

4. Setup
4.1 Attaching the Cable
- Identify the left (L) and right (R) earphone units and cable connectors. The cable connectors are typically marked with 'L' and 'R'.
- Align the 2-pin connector on the cable with the corresponding socket on the earphone unit. Ensure the pins are correctly oriented.
- Gently push the connector into the socket until it is firmly seated. Do not force the connection.
- Repeat for the other earphone unit.
4.2 Selecting and Installing Ear Tips
The correct ear tip size and type are crucial for comfort, sound quality, and noise isolation. The Titan X includes three types of silicone ear tips, each in three sizes (Small, Medium, Large):
- Balanced Sound Ear Tips: For a neutral and versatile listening experience.
- Atmosphere Ear Tips (Bass-focused): Designed to enhance bass response.
- Candy Ear Tips (Vocal Clarity-focused): Optimized for clearer vocal reproduction.
- Gently remove any pre-installed ear tips by twisting and pulling.
- Choose an ear tip size that provides a snug, comfortable fit and forms a good seal in your ear canal. Experiment with different sizes and types to find your preferred sound and comfort.
- Push the chosen ear tip onto the nozzle of the earphone until it is securely attached.

5. Operating Instructions
5.1 Connecting to an Audio Source
The DUNU Titan X (3.5mm Jack version) is compatible with a wide range of devices:
- Plug the 3.5mm jack of the cable into the headphone output of your audio source (e.g., smartphone, laptop, digital audio player, gaming console controller).
- Ensure the connection is secure.
- Adjust the volume on your audio source to a comfortable listening level before placing the earphones in your ears.

5.2 Wearing the Earphones
- Insert the earphone units into your ear canals, ensuring a comfortable and secure fit. The cable is designed to be worn over the ear for better stability and reduced microphonics.
- Adjust the cable behind your ear for optimal comfort.
5.3 Volume Control
Control the volume directly from your connected audio device. The Titan X earphones are highly sensitive and do not require an external amplifier for most devices.
6. Maintenance
6.1 Cleaning the Earphones and Ear Tips
- Regularly clean the ear tips with a soft, damp cloth. For deeper cleaning, remove the ear tips and wash them with mild soap and water, then allow them to dry completely before reattaching.
- Use the provided cleaning brush to gently remove any earwax or debris from the earphone nozzles.
- Wipe the earphone casings with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials, as the alloy casing is scratch-resistant but can be damaged by strong solvents.

- Avoid sharp bends or excessive pulling on the cable.
- When not in use, store the earphones and cable in the provided storage bag to prevent tangling and damage.
