Strap in and stop thinking about the mic. This RE3-BPHW set pairs the RE3 bodypack transmitter with the HW3 supercardioid headworn microphone: a condenser element with a wide 30 Hz-18 kHz range, a shock-mounted head to shrug off handling noise, and an adjustable headband that stays put through real movement. The transmitter runs a phase-locked loop with switchable 10/50 mW RF and two AA batteries, tuned 560-596 MHz. Fitness floor, stage, lecture hall: sweat through it and stay clear.
