Liquid silicone-encased bone conduction headphones

Product Overview

The bone conduction headphones consist of three core components: the transducer unit, the ear hooks, and the rear body. Each part is precision-engineered to balance comfort, durability, and acoustic performance.

Transducer Unit: Encased in a full silicone sleeve and crafted using a solid-state molding process. The sleeve and transducer are engineered with tight tolerance matching to ensure a precise fit upon assembly; this not only enhances the skin-friendly feel but also effectively isolates external vibrations, ensuring pure sound output.

Ear Hooks: Constructed with a plastic core encased in silicone using Liquid Silicone Rubber (LSR) over-molding technology. The seamless, fully enclosed structure prevents moisture and sweat ingress, while the flexible silicone surface offers a gentle touch against the ear, ensuring a lightweight and secure fit even during prolonged use.

Rear Body: Features a memory titanium alloy core wrapped in silicone, created via a solid-state in-mold forming process. The memory titanium core allows for flexible bending to accommodate various head shapes and ear sizes, while the outer silicone layer provides flexible protection; the design withstands repeated twisting and bending without deformation or breakage.

Core Advantages

1.Crafted from import-grade Liquid Silicone Rubber (LSR) that meets FDA and ISO 10993 biocompatibility standards, the material offers a texture as smooth as a baby's skin, effectively eliminating issues like allergic reactions or chafing caused by prolonged wear.

2.The entire device is encased in silicone, achieving an IP68+ waterproof rating that ensures worry-free performance during activities such as swimming, diving, and surfing, fully satisfying rigorous waterproofing requirements.

3.The silicone’s inherent softness and comfort—wrapping 360° around the headset body—provide a comfortable, weightless wearing experience and a skin-friendly feel. This silicone casing also dampens sound waves generated by internal vibrations, further reducing discomfort.
