The silent room

Modern office spaces are open and collaborative. Employees only feel comfortable if
acoustics are optimized and opportunities for retreat are created. The EchoBox® by
SYMA creates this connection. And because modern office spaces are flexible, the
EchoBox® can be set up in just a few simple steps and without tools. A silent room
within a room.


In the open office, telephone calls and video calls at the desk are extremely unsuitable. The soundproof EchoBox® provides privacy and less noise. A room within a room for short and focused conversations, while standing or sitting. Thanks to the integrated height-adjustable desk, there is also room for documents or a laptop. The conversation booth can be assembled without tools, its seven parts weigh only 42kg.

The cooperation

ECHOJAZZ high-performance acoustic panels are the ideal wall surface for a sound-protected box. SYMA system components are known worldwide in exhibition stand construction and architecture. Then the two Swiss companies met – at an exhibition stand. SYMA engineers immediately took on the task of creating the ideal frame for the acoustic panels. Together, they came up with the EchoBox® consisting of seven parts with a tool-free magnetic connection that combines the expertise of both companies. Built on engineering skills, a subtle design approach and flexible applications in mind.

Acoustic Inspiration

EchoBoard® is made of 100% PET with a recycled content of at least 50 PET bottles per square meter. It is recyclable, taken back and further processed into EchoFlakes®.
Customised high-performance sound absorbers for a noticeable improvement in well-being and room quality. The EchoBoards® by ECHOJAZZ are made from recycled PET bottles.
100% Swiss Design, 100% Zero Waste.

Inspiring Systems

At SYMA we have developed our own intelligent approach. Our name is synonymous with this system. Yet each of our developments is also rooted in inspiration – and is designed to be inspirational. In real terms, SYMA offers profile systems with connector technology and accessories for applications in exhibition stand construction, architecture and industry. SYMA’s modular system components provide practically unlimited freedom of design.
