What to know before buying
Listing details to confirm
Listing details conflict on pickup pattern: specifications call it unidirectional, while feature and description text call it omnidirectional or cardioid. The connector is also listed as both TA4F and USB, although the manufacturer text specifically describes a TA4F (TQG) connection for Shure bodypacks. Treat the listed frequency range, battery requirement and dimensions as unconfirmed details, and confirm the exact variant and compatibility before purchase. A wireless bodypack is sold separately.
