Optimal Fit and Comfort
The headphones feature a fine adjustment mechanism that allows the nozzle to rotate 360 degrees, ensuring an optimal fit for various ear shapes. Included Spiral Dot+ earpieces, made from SMP iFit material, provide a natural and comfortable fit, enhancing sound expression by minimizing unnecessary pressure.

Durable and Detachable Cable
The HA-FD01 utilizes an MMCX terminal for its detachable, grooved OFC (Oxygen-Free Copper) cable. This design improves both strength and durability, while also reducing tangling. The 3.5mm 24k gold-plated stereo mini plug ensures optimal signal transfer.

Setup Guide
1. Attaching the Cable
Align the MMCX connector on the cable with the port on each earbud. Gently push until you hear a click, ensuring a secure connection. The cable is designed to be detachable for easy replacement or storage.
2. Selecting Earpieces
Choose the Spiral Dot+ earpiece size (S, MS, M, ML, L) that provides the most comfortable and secure fit for your ears. A proper seal is crucial for optimal sound quality and bass response. Gently push the earpiece onto the nozzle until it is firmly seated.
3. Customizing Sound with Nozzles
Experiment with the Titanium, Brass, and Stainless Steel interchangeable nozzles to find your preferred sound signature. To change a nozzle, gently twist and pull the current nozzle off the earbud. Then, align the desired nozzle and push it firmly onto the earbud until it clicks into place. Each material offers a unique acoustic profile:
- Titanium: Often associated with a bright and detailed sound.
- Brass: May provide a warmer sound with enhanced bass.
- Stainless Steel: Typically offers a balanced and neutral sound.
4. Adjusting for Fit
The nozzle of the HA-FD01 can rotate 360 degrees. Adjust the angle of the earbud to achieve the most comfortable and stable fit in your ear. This also allows for wearing the headphones with the cable hanging down or looped over the ear.
Operating Instructions
Connecting to Your Device
Insert the 3.5mm stereo mini plug into the headphone jack of your audio device (smartphone, tablet, computer, digital audio player, etc.). Ensure the plug is fully inserted for proper audio transmission.
Volume Control
Adjust the volume directly on your connected audio device. Start with a low volume level and gradually increase it to a comfortable listening level to prevent hearing damage.
Care and Maintenance
- Cleaning Earpieces: Regularly remove the earpieces and clean them with a soft, damp cloth. For deeper cleaning, they can be washed with mild soap and water, then thoroughly dried before reattaching.
- Cleaning Earbuds: Use a dry, soft cloth to wipe the exterior of the earbuds. Avoid using harsh chemicals or abrasive materials. Ensure no moisture enters the driver unit.
- Cable Care: While the grooved cable is designed to resist tangling, avoid excessive bending or pulling. Store the cable neatly when not in use.
- Storage: When not in use, store your headphones in the provided carrying case to protect them from dust, dirt, and physical damage.
- Avoid Moisture: These headphones are not water-resistant. Keep them away from water, humidity, and extreme temperatures.
