Shure A55M Isolation and Swivel Shock Stopper Microphone Mount

The Shure A55M is a shock stopper mount that pairs a sturdy microphone clip with built-in isolation, giving handheld microphones a clear path to the preamp by blocking unwanted bumps and stand noise.

Inside the mount, a vibration control system cuts mechanical rumble by more than 20 decibels. Performers and engineers notice the difference immediately, whether that vibration comes from a crowded stage, a wooden podium, or a boom arm that keeps getting nudged during a podcast.

The circular grip surrounds the microphone body rather than squeezing it from one side, so it holds steady without scratching finishes. It works with barrels measuring 25 to 30 millimeters, which means popular Shure models such as the SM57, SM58, and KSM109 drop right in, as do many microphones from other brands that share the same diameter.

Set-up is simple. Thread the A55M onto any standard stand or boom, swivel the built-in adapter until the capsule is aimed exactly where you need it, then lock it in place. Studio owners appreciate how quickly it fits into existing rigs, while live sound crews like its ability to travel easily and survive daily loading and unloading.

From rehearsal rooms and club stages to broadcast booths and field kits, the A55M provides a practical shield against the small vibrations that can ruin a take or a broadcast. It is a no-nonsense accessory that keeps the focus on the performance instead of the noise.
