Sennheiser 300 Series Wireless In-Ear Monitor
Like the wireless microphone, the wireless In Ear Monitor (IEM) system has allowed performers the freedom to command a greater area of the stage and beyond without the danger of inducing feedback into the microphone, or moving out of earshot of the monitor speakers. The advantages of clarity and fidelity offered by IEM will be obvious to any performer who has strained to hear their voice or instrument in a monitor mix, against a background of ever increasing on-stage volume levels. A further advantage, for artist and sound engineer alike, is that completely individual monitor balances can be transmitted to each performer. 

Now Sennheiser has made this latest professional IEM technology available to everyone with evolution IEM. Even more amazing, evolution IEM improves the quality, build and flexibility of IEM technology to provide the highest, interference-free transmission reliability and audio quality, and to make it simple to operate multiple IEM systems simultaneously. Each set consists of a stereo in ear phone with a special earpiece that is attached to the portable bodypack receiver (custom ear molds can also be used with the receiver pack). The system receives monitor sound from the fixed transmitter.

The Evolution wireless IEM system consists of three main components: At the heart of the system is the SR 300 IEM stereo rackmountable transmitter. The rugged EK 300 IEM stereo pocket receiver has been specially designed for rough stage use - its modern controls, adapted to live stage work, ensure a straight-forward, intuitive operation. Both transmitter and receiver feature a special "lock mode" function to prevent operating errors.
