Ulanzi A21 USB-C Microphone — dual pack, 2 units, black (A053)

The Ulanzi A21 USB-C Microphone dual pack contains two compact, black USB-C microphones designed for direct digital connection to compatible USB-C devices. Each microphone provides a plug-and-play solution for recording clear audio without the need for separate audio interfaces or adapters. The twin set is intended to simplify dual-input workflows such as interviews, two-person podcasts, and paired-stream setups by offering two identical microphones that can be used simultaneously for synchronized capture.

Advantages

Both microphones in the pack connect via USB-C for direct digital audio transfer, eliminating analog conversion and reducing setup complexity. The compact design makes them convenient for mobile recording and on-camera mounting, while identical acoustic characteristics ensure balanced audio when both channels are used together. The set supports quick plug-and-play operation with compatible smartphones, tablets, and computers that accept USB-C audio input.

Suitable for

• Interviews and two-person recordings
• Live streaming and video calls
• Vlogging and on-camera audio capture
• Podcasting with separate microphones for each speaker
• Content creation on USB-C smartphones, tablets, and laptops

Key specifications

How to use

Connect each Ulanzi A21 microphone to a USB-C port on the recording device. For two-person setups, plug both microphones into available USB-C ports or use a compatible hub that preserves individual audio channels. Select the microphones as the active audio inputs in your recording or streaming application. Position the microphones close to each speaker for clear capture and avoid obstructions between the sound source and the microphone capsules. No external power or adapters are required when connecting to devices that support USB-C audio.

Usage recommendations

For best results, use the dual pack to assign one microphone per speaker and set input levels in your recording software to achieve balanced gain. If using a smartphone or tablet with a single USB-C port, employ a compatible multiport adapter that supports audio devices and ensures each microphone is recognized as an individual input. Store the microphones in a protective case when not in use to prevent damage and keep connectors clean.
