The helmet-independent neckband headset from CeoTronics is also available as an ATEX model. 

It features a low-profile design and minimal unit weight. At just 22 grams, it is naturally very comfortable to wear. Thanks to special adjustable wire, wearers can configure the unit to match their exact head shape. It is comfortable to wear under helmets or masks and is equipped with a sound-conducting tube that routes the loudspeaker signal directly into the ear aperture. 

The use of earbuds guarantees perfect hearing even in noisy environments. Voice transmission in areas with high levels of noise is ensured thanks to the use of the noise-compensating boom microphone.
