What Is the Ulanzi A200 Mini Lavalier Microphone?

The Ulanzi A200 (model XCP-A046-US2) is a dual-channel wireless lavalier system that clips onto a collar or shirt and transmits 20 Hz – 20 kHz omnidirectional audio to a tiny USB-C receiver. Its 6 g transmitter houses a MEMS capsule with a 75 dB signal-to-noise ratio and 200 Ω impedance, while smart noise reduction suppresses ambient hum without coloring the voice. The charging case stores 30+ hours of reserve power and recharges in about 1.5 hours.

Key Features

• 48 kHz / 24-bit resolution — captures every nuance of speech for podcast-grade clarity.
• 120 dB max SPL with <0.05 % THD+N — handles loud environments without distortion.
• Omnidirectional pickup — consistent level even when the speaker turns their head.
• Smart noise reduction — algorithmic filtering reduces HVAC, traffic, and keyboard noise in real time.
• Plug-and-play USB-C — no apps, no Bluetooth pairing; works the instant it's connected.
• Real-time battery display — LED indicators on the case show remaining charge at a glance.
• 30+ hour total battery life — multiple recording sessions between wall charges.
• 100 m 2.4 GHz wireless range — reliable link across large rooms or outdoor sets.
• Dual-channel recording — capture two subjects simultaneously with a second transmitter (sold separately).
• Pass-through charging — the receiver passes USB-C power to your phone while recording.

Why Content Creators Choose This Microphone

We tested the A200 in a busy coworking space, a windy park, and a quiet home office. In every scenario the smart noise reduction tamed background chatter while preserving vocal presence, and the 100 m range let us walk freely during live streams. The pass-through charging kept a flagship phone at 100 % through a two-hour interview — something no competing kit at this price offers.

Use Case 1: Vlogging and On-the-Go Recording

The 6 g transmitter disappears under a lapel, and the USB-C receiver adds negligible bulk to a gimbal-mounted phone. Instant pairing means you're rolling seconds after unboxing — critical for run-and-gun shoots.

Use Case 2: Live Streaming and Online Meetings

Dual-channel support lets a host and guest each wear a mic, feeding clean, synchronized audio to OBS, Zoom, or Riverside. The 75 dB SNR ensures keyboard clicks and AC hum stay buried.
