Visão Geral

The SC 230/260 ATC/C3 AG series of robust headsets is designed to meet the daily challenges faced by Air Traffic Controllers and C3 operators. Hearing and being heard clearly is fundamental for safety and confidence in ATC/C3 environments and the series delivers on both counts, thanks to Sennheiser’s legendary audio expertise. A unique ear cup shape and a built-to-last design make the headsets both comfortable enough for long hours of wearing and tough enough to withstand years of daily use. A fully adjustable metal headband with numbered grooves and soft leatherette ear cups make finding and keeping the perfect fit simplicity itself.

And with name tag personalization, it’s always possible to identify your own headset. Sennheiser ActiveGard® technology protects users’ hearing against acoustic injury caused by a sudden sound burst on the line, with no risk of communication drop-out.
