The Sennheiser ew 300 IEM G3 is designed for crisp and vivid live sound. The system is rugged enough for heavy touring, and features include automatic frequency management, infrared transmitter sync, expanded switching bandwidth, and soundcheck mode. The ew 300 has an adaptive-diversity receiver - the receiver pack uses the headphone cable as a secondary antenna for better reception. Ear-canal phones, with various ear-fitting pads for an individual fit, reproduce the signal from the adaptive diversity receiver precisely, and pass-through outputs allow easy splitting of the input signal to travel to other devices. The 5 band equalizer integrated in the transmitter also allows you to personalize the sound and the set can be monitored and remotely controlled with Sennheiser’s “Wireless Systems Manager” software thanks to the built-in Ethernet port on the stereo transmitter.
