San Sebastián, September 8, 2025 – Three consecutive nights, over 40,000 total spectators, and an arena transformed into a sea of Silentsystem wireless headphones: the “Mitoaroa II” format by the band ZETAK has set a new world record for silent concerts.

From September 5 to 7, the Illunbe Arena in Donostia–San Sebastián hosted the largest “silent” event ever held, with 13,500 wireless headphones distributed each night to the audience, who experienced a one-of-a-kind show in total sound immersion.

What made this achievement possible was the technology of Silentsystem, a leading company in wireless audio systems, which supplied and managed the fleet of SX-839 V2 HiFi headphones. These models, designed to ensure high fidelity, signal stability, and extended battery life, made it possible to synchronize thousands of listeners simultaneously with a consistent experience in every corner of the arena.

The event required meticulous organization: distribution and collection of tens of thousands of headphones, radio frequency management, charging logistics, and sanitization. A team effort that involved dozens of technicians and volunteers to ensure precision and smooth execution.

The result was astonishing: outside, near silence; inside, a concert with crystal-clear and powerful sound, capable of transforming the way live music is experienced.

A World Record

Never before had a silent concert reached such dimensions. With over 40,000 attendees in total, ZETAK and Silentsystem made history, demonstrating how wireless technology can expand the possibilities of live shows, respect the urban sound environment, and offer new perspectives to the entertainment industry.

Quotes

“With ZETAK we have taken live music to a new dimension: a silent concert on the outside, but extraordinarily powerful and shared on the inside. For us at Silentsystem España, it is a source of pride to have made this world record possible right here in the Basque Country.”
– Fabrizio Baraldo, CEO Silentsystem España S.L.
