Shure BLX14R/SM35-H9 Wireless Headset Microphone System

The Shure BLX14R/SM35-H9 is a complete wireless headset microphone system designed for presenters, performers, fitness instructors, and worship leaders who need reliable hands-free audio. At its core is the SM35 headset condenser microphone, which provides clear, consistent vocal pickup in a lightweight, adjustable design that stays secure during active movement. The microphone connects to the BLX1 bodypack transmitter, a compact belt-worn unit that runs up to 14 hours on a pair of standard AA batteries — enough to cover even the longest events without a battery swap.

The BLX4R receiver is a single-channel, rack-mountable unit that fits standard 19-inch equipment racks, making it easy to integrate into existing AV setups in venues, houses of worship, and conference rooms. The system operates with a range of up to 300 feet line-of-sight, and supports up to 12 compatible channels per frequency band for multi-system deployments. Setup is deliberately straightforward — Shure designed the BLX series for users who need professional sound without a steep learning curve. The system ships as a complete package with all mounting hardware, cables, batteries, and the headset mic, so there's nothing additional to purchase to get started. For anyone stepping into professional wireless for the first time or expanding an existing setup, the BLX14R/SM35 delivers Shure's trusted audio quality in an accessible, complete package.
