Features:
The Ulanzi A21 Wireless Microphone is a professional-grade wireless audio solution designed for content creators, vloggers, interviewers, livestreamers, and on-the-go journalists. With its ultra-lightweight button-style transmitters and fully wireless system, it delivers high-clarity audio without the tangle of cables.
Each microphone features 32 kHz/24-bit high-resolution sampling and a 360° omnidirectional pickup pattern, ensuring natural, rich sound from all directions. Integrated AI noise reduction intelligently minimizes background noise for clearer voice capture — especially helpful in crowded or outdoor settings. The included furry windshields further improve wind noise rejection when recording outdoors.
Operated on the reliable 2.4 GHz band, the system maintains a strong wireless link up to 100 m (open area). The compact charging case not only protects the microphones but also provides multiple full recharges, making this kit ideal for all-day shoots without frequent charging breaks.
Whether you’re shooting interviews, TikTok/Reels content, podcasts, or event coverage, the A21 system delivers dependable performance in a sleek, minimalist design.
