Audio Technology and Design
The Mi Piston Basic headphones incorporate advanced design elements for enhanced audio performance and durability.
- Aerospace-Grade Metal Diaphragm: The diaphragm utilizes a combination of aerospace-grade metal and PET for a balanced and solid sound profile, optimized for various music genres.
- 3rd Gen Balanced Damping System: This unique system improves sound and airflow by separating airflow at the front of the chamber and allowing sound through the back, resulting in a mellow and transparent audio experience.
- Aluminum Sound Chamber: The earbud housing is crafted from lightweight, scratch-resistant anodized aluminum with a finely engraved CD-like pattern for a sleek finish and improved grip.
- Tangle-Free Flat Cable: The cable features an inner Kevlar wrapping for durability and an outer PET lining, making it smooth, resistant to bends, and less prone to tangling.


Maintenance
- Cleaning: Regularly clean the ear tips with a soft, dry cloth. For deeper cleaning, remove the ear tips and wash them with mild soap and water, ensuring they are completely dry before reattaching.
- Storage: When not in use, store your headphones in a clean, dry place to prevent damage and tangling.
- Avoid Moisture: While the cable is designed to be durable, avoid exposing the headphones to excessive moisture or liquids.
Troubleshooting
- No Sound:
- Ensure the 3.5mm jack is fully inserted into your device's audio port.
- Check your device's volume settings.

- Ensure ear tips are correctly sized and form a good seal in your ear.
