Shure A25D SM57/58 Microphone Clip Black

The Shure A25D is a split-collar microphone clip machined to accept microphones with a barrel diameter of 3/4 inch or larger — most directly the SM57, SM58, SM86, and SM87. Its clamping mechanism is a thumbscrew-tensioned split collar that encircles the mic barrel; tightening the screw compresses the collar for a friction-based hold that resists both rotation and gravitational droop. The clip body terminates in a 5/8-inch female thread with a 3/8-inch reducer adapter included, giving it compatibility with the full range of standard American and European mic stand hardware. At 9 grams, it introduces no meaningful mass into a boom arm's weight equation.

In practice, the A25D is the functional baseline against which all other clips in this diameter class are measured — because it is literally the clip Shure ships with its most-deployed dynamic microphones. Houses of worship, touring companies, recording studios, and broadcast facilities maintain stock of it as a consumable. Its value is not in innovative engineering but in interchangeable standardization: when a clip breaks mid-soundcheck, a new A25D threads on identically to the one it replaces, with no adjustment required. For any facility running SM57s on drum kits and SM58s on vocal stands, keeping a spare pack of A25Ds is straightforward infrastructure maintenance.
