Hearing excellence since 1965

Long-term dedication to R&D has positioned Univox at the forefront of the induction loop industry. A combination of high voltage, high current and strong long-lasting casing make our loop amplifiers unparalleled in the world.

Univox by edin, the world’s leading expert and producer of high quality induction loop systems, created the very first true constant current loop amplifier 1969. Ever since, our mission is to serve the hearing aid community with the highest degree of service and performance with strong focus on Research and Development for new technical solutions.

The first products manufactured consisted of systems that had to be installed by professional technicians. Since several years Bo Edin AB also has developed products that don’t need to be installed. These products are sold directly to end-users.

Initially the company cooperated with the largest distributor of medical care products in Sweden, LIC (owned by Swedish County Councils). The assistive hearing devices developed and produced by Bo Edin AB were distributed mainly by LIC. In December 1992 this cooperation was put to an end, and Bo Edin AB started direct sale and distribution to existing markets and customers in Sweden.

Thanks to a strong technology portfolio and cutting edge products – in some cases world-leading – the exports began to grow in the early 70’s. Exports accounts for approximately 30% of the total turnover.

The export countries include Norway, Denmark, Finland, United Kingdom, the Netherlands, Germany, Hungary, Poland, Italy, Switzerland, USA, Australia, New Zealand and China (HK). Today Bo Edin AB produces more than 10,000 loop amplifiers per year.

Univox method included in international standard Bo Edin AB focuses on the development of new techniques in the field and plays an active role in international standards work for loop systems.

With an active role in the work group TC-29/MT-20, Bo Edin AB (Univox) is deeply involved in the continuous working process of the induction loop standard IEC 60118-4.

A new standard IEC 60118-4:2006, is now realized and was unanimously approved September 1 2006 by the IEC members from all parts of the world. The new standard adopted in Sweden by SIS March 1 2007, has yet to be adopted in every member country.

This means that the Univox method using ITU artificial speech is now included in the new international standard for induction loops!


Safety policy

Every single active product goes through our final check procedure, making sure that all our products will be delivered with the highest quality and safety standards.


Environmental policy

Our environment is of great importance to us and we work actively with environmental issues on a daily as well as on a long-term basis.
