The Electro-Voice R300-E is a cost-effective wireless omnidirectional headset microphone system well suited for tabletop use, or as part of an AV installation, in small- to medium-sized conference centers, educational facilities, and performance spaces.

The R300-E includes the R300 antenna-diversity receiver along with the BP-300 bodypack transmitter and an HM3 headworn condenser microphone. The mic's forgiving omnidirectional polar pattern picks up sound from all around the capsule, helping to ensure consistent levels even when the talent turns away from the capsule. The receiver has a 150' operating range and features 32 pre-programmed frequencies to scan for optimal transmission, along with removable antennas that allow the user to rackmount the unit (requires mounting kit and antenna cables—available separately).

The ClearScan feature on the R300 automatically searches for the ideal operating frequency, while the EZ Sync button locks the transmitter to the correct channel via infrared. The system's antenna-diversity technology helps to reduce noise and interference by comparing the incoming signals on the two antennas and using the stronger one. The receiver features both 1/4" phone and XLR outputs on the rear, and a power supply is included. The HT300 transmitter operates for up to 14 hours on a pair of AA alkaline batteries.
