Custom Silicone Overmolded Earphone Protector – Skin-Friendly Silicone Sleeve for Sports

The Custom Silicone Overmolded Earphone Protector is designed to deliver superior comfort, reliable grip, and long-lasting protection for your earbuds. Made from medical-grade Liquid Silicone Rubber (LSR), it ensures a hypoallergenic, skin-friendly touch while maintaining exceptional durability for daily use.

Our silicone overmold provides a soft, non-slip coating that conforms naturally to your ear’s shape, reducing pressure points during extended listening sessions. Whether you’re running, commuting, or in the office, your earphones stay comfortably in place without irritation.

Soft-touch matte finish for a smooth, skin-like feel.

Flexible elasticity that adjusts to subtle ear movements.

Reduces ear fatigue compared to hard plastic or metal surfaces.

Engineered to guard against scratches, scuffs, and minor impacts, this silicone layer helps maintain the pristine condition of your earbuds. The overmold also prevents dust accumulation, prolonging the life of your device.

Shock-absorbing and impact-resistant design.

Protects against sweat, humidity, and light rain.

Anti-slip surface improves grip during intense activities.

Ideal for sports and outdoor use, the medical-grade silicone forms a moisture barrier that protects sensitive components from sweat and splashes. Despite its tight seal, it preserves full sound quality and microphone clarity.

Resistant to UV exposure and temperature changes.

Easy to clean—just rinse with water and mild soap.

Non-toxic, BPA-free, and compliant with global safety standards.

Using high-precision LSR injection molding and custom overmold tooling, we produce protectors that fit exactly to your earphone model. Every curve, button, and sensor is considered to ensure a seamless integration without blocking any features.

Compatible with in-ear, semi-open, and open-ear earbuds.

Customized cutouts for charging ports, sensors, and buttons.

OEM/ODM fit customization available for brand-specific designs.
