Anti-Tangle Cable Design
The earbud cable is constructed from soft and elastic aerospace TPE hollow material, reinforced with copper wire and fiber. This design provides excellent durability, abrasion resistance, and significantly reduces tangling, ensuring a smooth user experience, especially during gaming with 0 latency.

IP67 Dustproof and Waterproof Rating
The earbuds are rated IP67, offering protection against dust ingress and immersion in water up to 1 meter for 30 minutes. This makes them suitable for use during workouts or in light rain, but they are not intended for swimming or prolonged submersion.
Maintenance and Care
- Cleaning: Regularly clean the ear tips with a soft, damp cloth. For the earbud nozzles, gently wipe away any earwax or debris using a dry cotton swab. Do not use harsh chemicals or abrasive materials.
- Storage: When not in use, store the earbuds in the provided protective case to prevent tangling and damage.
- Water Exposure: While IP67 rated, avoid unnecessary exposure to water. If they get wet, dry them thoroughly before storing or using again. Do not charge or connect to a device if the jack is wet.
- Cable Care: Avoid sharp bends or excessive pulling on the cable to maintain its integrity.
