    "who_should_skip": "Users needing a small microphone, phantom-powered active output, cardioid-only isolation, or rugged handling around strong air blasts.",
    "fit_notes": "Use a quiet, high-gain preamp with suitable input impedance, disengage phantom power where possible, and protect the ribbon from blasts of air.",
