This wireless neckband earphone is a performance-oriented audio accessory designed for users who need a combination of long battery life, physical stability, and high-quality sound for active lifestyles. Ergonomic & Structural Design Contoured Neckband: The device features a flexible, U-shaped neckband crafted from a lightweight, skin-friendly polymer. This design allows the unit to rest naturally around the collarbone, distributing weight evenly to ensure comfort during extended wear. Precision In-Ear Fit: The earbuds are designed with an ergonomic tilt-often angled at 45 degrees to match the natural shape of the ear canal. Combined with soft silicone ear tips, this provides a secure seal that aids in Passive Noise Isolation. Magnetic "Tangle-Free" Storage: Each earbud contains a built-in magnet. When not in use, they snap together to form a "necklace" around the neck, preventing the cables from tangling and ensuring the device stays secure while you are walking or running.
