The MH series headsets and headphones provide the latest design in headset technology from RTS / Telex. They provide clear communications for professional applications, including live, remote or studio broadcasting, film, television or theatre intercom communications. With a rugged, modular design and lightweight construction, they are a multi-functional headset that goes way beyond live studio and theatre venues.The modular design allows you to interchange modules to allow for the best headset configuration for any environment. The noise-cancelling microphone, combined with either passive (MH300 series) or active (MH400 series) headset transducers, provides clear and precise communication in noisy environments. The use of different modules allow for a communication headset to be easily converted to a studio grade monitoring headphone, or adapted to be utilised with standard MP3 players. Additionally, all user contact points (i.e. ear cup cushions, temple pads, headband cushions and windscreen) are completely replaceable, allowing for sanitary use.
