nACRe ComTac IV is not a waterproof, but a splash-proof set, so it can be used e.g. when it rains, but it is not suitable for OTB operations. The left ear cup has an attached wire for the external radios. Speakers in Peltor ComTac IV are in form of ear plugs similar to 3M/Peltor Combat Arms. They end with an ear tip, which may have the form known from "semi-active" earplugs or of a foam cone. The first type is reusable (it is possible to clean them), while the second type is disposable. ComTac IV might come with boom, gooseneck or throat microphone as well. From the basic point of view ComTac IV does not differ from previous sets and may be folded into a handy "pack", so that it occupies little space when transported. A full set of Peltor ComTac IV weighs 238 g. IN-EAR HEADSETS It is probably the most advanced form of hearing protection available due to the tiny size of electronics responsible for control and sound filtering. A great majority of them is designed for the military and law enforcement, but some of the manufacturers also offer equipment for civilian world and industry. Active in-ear hearing protections, apart from a few exceptions, consist of earplugs with integrated microphone, speaker, noise-canelling insert and a control unit with the power supply. Very few exceptions (e.g. 3M/Peltor TEP-100) have electronics placed in each earplug (in fact, electronic circuit is duplicated). The main goal of manufacturers was to eliminate headband and ear cups that were, in some situations, inconvenient. It matters, especially when someone is using a helmet – in the case of earplugs, the type or shape of helmet is unimportant, since they are compatible with almost every model. Due to elimination of the heaviest elements, the user does not have to encumber his or her head, which is also of significant importance. www.fragoutmag.com
