Shure BLX24E/SM58-K3E

Shure BLX24E/SM58-K3E Wireless Microphone System — Pro Sound, No Cables

The Shure BLX24E/SM58-K3E is a complete UHF wireless handheld microphone system built around the legendary SM58 dynamic capsule. Designed for singers, speakers, and worship leaders who need freedom of movement without sacrificing vocal clarity, this set combines the BLX2 handheld transmitter with the BLX4 tabletop receiver on the K3E frequency band (606–630 MHz). Setup takes seconds thanks to one-touch QuickScan, and the system delivers the warm, present vocal character that has made the SM58 the most recognized stage microphone in the world.

What Makes This Wireless Set Stand Out

The pairing of the SM58 capsule with the BLX2 transmitter brings Shure's industry-standard vocal sound into a fully wireless workflow. Microprocessor-controlled internal antenna diversity on the BLX4 receiver keeps the signal stable across crowded RF environments, while the BLX2's -10 dB pad handles loud vocalists without distortion. Two AA batteries keep the show running for up to 14 hours straight, and the included PS24 power supply plus WA371 swivel adapter mean the system is ready to gig right out of the box.

The Shure BLX24E/SM58-K3E is the right choice for solo performers, worship teams, presenters, and small-venue sound engineers who want a reliable wireless vocal system without the complexity of pro-tier rigs. Singers stepping up from a wired SM58 will appreciate the familiar vocal character with the added freedom of wireless movement across the stage. Houses of worship, conference hosts, and mobile DJs benefit from the 14-hour battery life and QuickScan setup that gets the system running between sets in seconds. Up to 12 compatible systems can operate simultaneously in the same frequency band, making it a practical building block for growing multi-mic setups.
