The MA 24 Lk is a special headset designed to rest comfortably on the ear, offering a higher-performance speaker. Thanks to its design, the auditory field is not completely blocked, allowing the user to perceive surrounding sounds. The ergonomic design ensures optimal comfort and improved hygiene, minimizing discomfort during use. The headset wraps around the ear 360°, ensuring stability even during all sports activities or jobs that pose a high risk to worker safety due to working conditions (e.g., work at height on scaffolding, construction work on scaffolds, maintenance of cranes or towers, work on roofs or external stairs).
