Independent shopping perspective
Designed for presentations and stage use where a low-profile earset is wanted, this system pairs a beige MX153 headset microphone with a BLX bodypack and BLX4R receiver. The earset’s slender shaft and small microphone element keep the microphone visually unobtrusive. At the receiver, true-diversity two-antenna operation and channel scan support wireless setup, while XLR and 1/4-inch outputs connect it to the rest of the audio system. Road-rack installation hardware is included.
