If you are sourcing used professional audio gear for rental fleets, installs, or resale, the Shure SM58 is the one microphone that never sits on the shelf. The used price for an SM58 has stayed remarkably stable because the mic itself has not changed much in decades—and neither has demand. On the B2B wholesale market, you will typically see used SM58 units priced between $45 and $75 per piece, depending on condition, quantity, and whether accessories like the clip and pouch are included. Bulk lots of 10 or more can push the per-unit price closer to the $40 mark, while single units in like-new condition with original packaging may fetch $80 or more from buyers who need a quick replacement.
Compared to its main alternatives, the SM58 holds value better than most dynamic vocal mics. A used Sennheiser e835 often sells for $50–$65, and a used Audix OM2 sits around $55–$70, but neither moves as fast in wholesale channels. The SM58's price used is also supported by its legendary durability: a battered-looking unit that still passes a signal test can be a perfectly good rental stock item. For ranking purposes, expect to pay the most for units with original box and clip, then for clean units with minor cosmetic wear, then for units with scuffs but verified functionality, and the least for untested or parts-only microphones. Always confirm whether the grille is original or a third-party replacement—genuine Shure grilles add resale value.
When inspecting used SM58s, focus on the parts that fail first. Check the XLR connector for bent pins or looseness, test the on/off switch (if present) for crackle, and listen for any rattle inside the body that could indicate a loose capsule. The grille should be free of dents that press against the foam; a crushed grille can damage the capsule over time. Also verify that the threads on the body are not stripped, since replacement grilles will not seat properly. For bulk purchases, ask the seller for a photo of each unit's serial number and a short audio test recording—reputable wholesale sellers will provide this without hesitation.
Your next step is to request a quote based on quantity and condition tier. Most B2B sellers offer tiered pricing: 1–9 units at list, 10–49 at a discount, and 50+ at the best rate. Ask about shipping consolidation if you are buying from multiple suppliers in the same region, and confirm whether the seller includes the mic clip—it is a small part that frequently goes missing and costs extra to replace. If you need a mix of SM58 and SM57 for a rental package, ask for a combined quote; many sellers will bundle them to move inventory.
