The ew 300 IEM G3 Wireless In-Ear Monitoring System from Sennheiser is a wireless stereo audio system that provides terrific versatility in a compact package.
Both the transmitter and receiver have 1680 tunable UHF frequencies for interference-free operation. They also have a pilot tone squelch feature for eliminating interference when the transmitter is turned off.
An auto-lock on each unit prevents accidental settings changes, while an HDX compander provides high-quality audio. An integrated 5-band graphic EQ lets you shape sound to favor audio frequencies that you prefer. A mute function silences the audio.
The receiver operates on a pair of standard AA batteries, and also has external contacts points for charging a BA 2015 rechargeable accupack battery inside the receiver. A pair of IE 4 earphones are included so you can begin monitoring immediately.
