Overall RatingGood for the price / Solid budget dynamic microphone.
It is a respectable entry-level to mid-tier vintage dynamic mic — not studio reference quality, but surprisingly capable for its era and original low cost.Sound Characteristics
  • Tone: Clear with a slight midrange presence/boost that gives vocals a warm, forward quality. It has decent articulation without being overly harsh or "crispy" in most uses.
  • Frequency Response: 50 Hz – 15 kHz. It delivers natural-sounding voice with good intelligibility. Low end is reasonably full (not boomy), and highs are present but not overly bright or sibilant.
  • Polar Pattern: Unidirectional (cardioid) — good off-axis rejection, which helps reduce background noise and feedback in live/PA situations.
  • Strengths:
    • Excellent for spoken word, vocals in PA systems, amateur radio (ham), podcasting, and general announcements.
    • Handles close-miking well (proximity effect adds some warmth when speaking/singing close to the mic).
    • Durable and low-noise (typical of good dynamic mics).
