The DRC Series wireless earphones comprise a range of physical fittings and colours using high-quality microelectronic circuits and acoustic drivers. These are designed to level limit at 85dB to provide protection to the user from high sound levels that can be generated by the earphone; this figure can be changed to special order. This type of earphone needs to be chosen with care as the relatively low output level may not provide intelligible communications if the operator is working in an area of high ambient noise.
