ADDICTED TO GREAT SOUND PERFORMANCE
High-tech cables for strong connections
- Ready to use es-Linum® cable: Cut, stripped, tinned
- Standard cable ø0.9mm with 2, 3, 6, and 8 conductors
- For manufacturers of hearing aids, OTC hearing devices, IEM cables, and communication earpieces
Achieve the smallest, most powerful, and reliable connections with estron’s cable programme without compromising strength and durability
estron cables with multiple conductors
es-Linum® is a unique high-tech cable developed by estron with 2, 3, 6, and 8 conductors as standard, and up to 14 conductors in custom solutions. The cable is strong, thin, and almost invisible.
The cable is made from ESW™ - silver-plated copper wire and strengthening fibres. Extruded with formable Pebax the standard versions are only 0.9 mm in diameter.
The es-Linum is a high-performance cable and an excellent alternative to traditional tube solutions for enhancing sound quality. Its compact design minimises acoustic feedback, and the unique material properties effectively reduce sound waves and mechanical vibrations.
Additionally, the cable features a construction that prevents sweat, moisture, and earwax from entering, ensuring it won’t oxidise or turn green over time. Ideal for hearing aid, medical hearing, OTC hearing, earphones, communication earpieces, and similar micro applications. The cable is also tested and used for cochlear solutions.
The es-Linum cable is the unique foundation of estron’s custom RIC connectors, detachable Linum earphone cables, OTC RIC connector es-Hear, and es-Comm communication solutions.
Since its introduction in 2006, es-Linum has been utilised in millions of applications, with its quality and reliability consistently demonstrated.
