## Overview

The Shure BLX14/SM31 Wireless Microphone System delivers professional-quality audio with a robust 300 ft wireless range and an impressive 14-hour battery life. Designed for fitness and aerobics, it features a unidirectional SM31FH headset mic for clear vocal pickup, quick setup, and scalability with up to 12 channels per frequency band. Ideal for small venues and active professionals seeking reliable, wireless freedom.

## Description

WIRELESS FREEDOM, MADE SIMPLE. The ideal entry-level wireless microphone system for small venues. BLX Wireless Systems provide professional-quality sound with simple setup and an intuitive interface. Choose from a wide range of transmitter form factors (handheld, bodypack, headworn, lavalier, instrument clip-on) and use it with single- and dual-channel, as well as rack-mounted receivers.

Review: I have purchased two of these headsets in the past eight months, and both became defective with severe static noise, making them unusable in my yoga studio. No professional business can run a class with this kind of interference. On top of that, the headphone jack is now completely stuck in the receiver on both devices. If this happened to just one unit, I could understand, but the exact same issue occurring with both makes it clear this is a recurring design flaw—if not intentional. This forces customers to replace not only the headset but also the receiver, which is unacceptable. For the price charged, the durability and reliability of these products are extremely poor. It feels as though the products are deliberately designed to fail after only a few months. I strongly advise staying away from this product
Review: It's expensive & I can't compare to something less expensive because I just went for it.
