The MA 24 777 Pro is a special earpiece designed to comfortably fit around the ear, offering a more powerful speaker. Thanks to its design, the auditory field is not completely blocked, allowing for awareness of surrounding sounds. The ergonomic design ensures optimal comfort and increased hygiene, minimizing discomfort during use. The earpiece adheres to the ear, providing stability even during all sports activities or work involving high risk to worker safety due to working conditions (e.g., work at height on scaffolding, construction work on scaffolding, crane or tower maintenance, work on roofs or external stairs). Equipped with an adjustable mechanism, it can be used on both the right and left ears for a personalized experience. We use state-of-the-art cables with particular attention to internal structure and materials used, ensuring reliable and long-lasting performance.
