This Sirus Quad C 823 MKII is a decent budget-friendly option for conference rooms or lecture halls needing basic wireless audio. The gooseneck is surprisingly stable, and the cardoid pickup pattern helps isolate voices. It’s best suited for situations where portability and simplicity are key, and top-tier build quality isn't a primary concern.
