The SENA SF2 is a Bluetooth communication headset designed for helmet use, enabling reliable wireless communication between two workers at distances of up to 800 meters in open terrain. Thanks to Full-Duplex technology, both users can speak simultaneously without interruption.

The device is ideal for rope access technicians, arborists, industrial climbers, installation crews and service teams who require continuous and safe communication while working. It allows efficient coordination, task management and operational decision-making without using hands.

The SENA SF2 can also connect to a smartphone for making and receiving calls, streaming music or listening to navigation instructions. The Audio Overlay function allows simultaneous intercom communication and audio streaming.

Voice activation (VOX) enables hands-free operation. Up to two mobile phones can be connected at the same time.

A built-in digital signal processor reduces background noise and echo, ensuring clear communication even in demanding and noisy work environments.

The headset features a durable, weather-resistant construction suitable for professional daily use. It can also be operated while charging.
