The SM58 Vocal Dynamic Microphone

A legendary mainstay of live performances, the SM58 is the mic that set the world standard. Boasting a classic look and world-renowned engineering, the SM58 is a durable, versatile mic that handles vocals with clarity and precision. It features a uniform cardioid polar pattern that faithfully reproduces your vocals so that they sound their best. An integrated pneumatic shock mount absorbs handling noise, so your sound doesn’t get lost in vibration. Meanwhile, the iconic spherical mesh grille and the mic’s built-in pop filter protect your audio from wind and plosives. This ruggedly-built mic is designed specifically to handle the rigors of touring and travel, so you can take it anywhere with you and perform on the go with confidence. Also included with the SM58 is a break-resistant swivel stand adapter and a storage bag to protect it from dust or other debris while in storage.

The QLXD2 is ruggedly built and simple to set up. Boasting transparent 24-bit digital audio quality and incredibly efficient RF spectrum usage, this handheld mic transmitter quickly syncs with a wireless receiver over IR at the push of a button, then maintains its clear, uninterrupted signal over its full 100 m (330 ft.) range. And, when using just 2 AA alkaline batteries, you can enjoy up to 9 hours of continuous, wireless use.
