Estron
Them, Central Denmark Region (Midtjylland), Denmark · founded 1994
The company behind two ubiquitous IEM technologies: the ultra-thin Linum cable (2013) and the patented T2 connector (2016). A pure components supplier — not a consumer brand — whose parts appear in premium IEMs and major hearing aids alike. Its first customer was Danish hearing-aid giant Oticon.
Estron a/s is a Danish manufacturer of miniature components for the hearing-aid, audio, and communication industries. A litz-wire pioneer (in the hearing business ~30+ years), it produces ultra-fine litz wires, ultra-thin detachable cables (Linum), and micro plug-socket connectors (T2). In personal audio it is best known as the supplier behind Linum IEM cables (introduced 2013) and the patented T2 connector system, both widely used in premium in-ear monitors and earphones. It is a components/OEM supplier rather than a consumer brand.
