Ulanzi A100 Wireless Lavalier Microphone for Clear, Low-Latency Voice

The Ulanzi A100 Wireless Lavalier Microphone is a compact, creator-focused wireless audio system built to deliver natural, balanced voice capture for phones and cameras. Designed for vloggers, interviewers, live streamers, and professionals, it uses an omnidirectional pickup approach to capture speech with a consistent sound character—helpful when you need reliable audio even if your head position shifts slightly during recording.

With Bluetooth 5.3 + EDR, the A100 supports stable wireless transmission and low-latency audio delivery, making it easier to keep audio and video synchronized. This is especially useful for talking-to-camera content, mobile interviews, and on-the-go production where wired setups can slow you down or limit movement.

Noise Reduction and Frequency Response for Natural Voice

To improve clarity in real-world environments, the microphone supports 3-level noise reduction and ENC (Environmental Noise Cancellation). Instead of simply boosting volume, ENC helps reduce distracting background sounds, so your voice remains more intelligible in busy indoor spaces or outdoor settings with ambient noise.

The A100 is tuned for voice reproduction with a frequency response of 20Hz–20kHz, covering the full audible range needed for speech. Its sensitivity of -38±2dB supports accurate pickup, helping you maintain consistent recording quality whether you’re recording in a quiet room or a moderately noisy location.

Flexible Connection Options with 3.5mm and USB Type-C

The receiver connects through 3.5mm and USB Type-C, giving you practical compatibility across common devices. This makes the Ulanzi A100 a strong choice for creators who switch between smartphones and cameras, or who want one wireless lavalier setup that can adapt to different gear.

For example, you can use it for interview-style recordings where you want hands-free mobility, or for teaching and presentations where consistent voice capture matters more than dramatic audio effects. LED indicators also help you monitor status and connectivity at a glance, reducing setup time before you start recording.

Rechargeable Battery Design for Longer Sessions

Powered by a 3.7V, 800mAh (2.96Wh) rechargeable battery, the Ulanzi A100 is designed for efficient everyday use. Charging time is approximately 1.5 hours, so you can quickly get back to recording between shoots.

A practical advantage for multi-segment production is that it can charge both transmitters simultaneously (noted as charging both transmitters over twice), supporting extended recording sessions without constant interruptions. This is especially helpful for event coverage, long interviews, or content days where you don’t want to manage separate charging cycles.

Compact Build for Easy Carry and On-the-Go Setup

The system is built to stay portable: the case measures 112 x 62 x 30mm, the transmitter is 43 x 18 x 18mm, and the receiver is 48 x 25 x 13mm. Lightweight components—0.0088 kg for the transmitter and 0.0096 kg for the receiver—make it easier to pack into a bag and keep ready for quick setup.

If you’re choosing a wireless lavalier microphone for mobile content creation, the Ulanzi A100 is a convenient option because it combines wireless convenience with straightforward device connectivity. It’s a good fit when you want a clean, professional voice capture workflow without the hassle of cables, while still maintaining practical compatibility through 3.5mm and USB Type-C.

Warranty Support

The Ulanzi A100 Wireless Lavalier Microphone comes with a 6-month warranty as stated in the product information. Keeping the warranty sticker attached to the box is required to make a warranty claim.
