A large amount of counterfeit Shure microphones was confiscated recently by customs officials in Peru and Paraguay, according to a release from the company. Included in the seized products were knockoffs of famous Shure mics such as the SM57 and SM58.

Shure said that the seizures are part of an ongoing investigation by Shure and local customs and law enforcement agencies.

In Peru, Shure said, about 2,300 counterfeit microphones were seized as products were being imported. They included models C606, SM58 and PG58. Authorities also confiscated thousands of cables and accessories, all marked with Shure’s trademark.

The products were being imported by Fabi Export and Import, a company that is not an authorized Shure distributor or reseller, according to Shure.

In Paraguay, customs officials raided resellers in Ciudad del Este including Music Shop, Music Brasil SA and Musical World. Products seized included fake SM57, SM58, Beta57A and Beta58A microphones as well as PGX digital wireless system components.

General Manager, Shure Americas Business Unit, Mark Humrichouser explained that Shure will “take vigorous action against counterfeiters worldwide.”
