The NB 1000 is the most cost efficient solution of the NB series. This lightweight neck holder headset is usable in various environments and made for professional use. It provides high wearing comfort and firm hold at the same time. High quality acoustic components take care of sound understanding, even in noisy environments.The electronic adaptation to specific analogue or digital radio devices is integrated into the inline-send button (PTT-16). Furthermore, the PTT-16 provides VOX-functionality for automatic voice controlled speaking/ listening. Along with lightweight helmets that do not cover the ears, e.g. bicycle helmets or helmets for construction work, the lightweight design of the neckband NB 1000 offers high wearing comfort. The sensitive electrets microphone still works when wearing respirator masks.Another benefit to increase the wearing comfort is the adjustable neck holder. Upon request, the lightweight send button PTT-16, delivered by standard can be replaced by the PTT-8 (Part No. 0110019-89).
