KSM9 microphones capture vocal subtlety with extraordinary detail to deliver clear articulation, functional flexibility and precise vocal reproduction for live performance. KSM9 microphones offer exceptional consistency across all frequencies, providing more gain before feedback, and minimizing proximity effect. With wired and wireless options and a choice of champagne and charcoal grey finishes, KSM9 offers the best combination for every performance. Shure UHF-R Wireless Systems feature KSM9 as the premier choice in handheld vocal microphones. KSM9 microphones are built to Shure's exacting endurance standards, renowned worldwide and proven night after night, center stage.

UHF-R handheld transmitters boast a rugged, lightweight construction and an antenna design which advances RF transmission reliability. The UR2 is offered with SM58®, SM86, SM87A, Beta 58A®, Beta 87A™, Beta 87C™, and KSM9.
