Code Red Battle Zero-NX BM Hybrid Bone Conduction Headset Black. The hybrid bone conduction speakers are positioned in front of the ears and push sound through the air into the ear canal. The speakers do not block your ears thereby improving situational awareness. The open ear design of the Battle Zero-NX BM not only contributes to situational awareness but also facilitates the use of foam hearing protection or electronic earbuds/hearing protection alongside the headset. The Battle Zero-NX BM is designed with a separate configuration from the helmet enabling communication even when the user is not wearing the helmet. This works great for Law Enforcement and other tactical teams. Features a US NATO plug.
