The omnidirectional version is most common in applications where feedback issues are not very likely. The microphone can be worn without a windscreen as the omnidirectional capsule provides excellent wind noise rejection. The E6i is set apart from the original E6 with its softer flexible boom and silicon ear-pads. The flexible boom provides ease of boom adjustability to accommodate multi-user applications. A wide variety of colors and connections are available for use with various wireless transmitters. This version is tan and features a Switchcraft TA4F connector for Shure transmitters.
