Main Features：

48kHz/16bit Recording, CD-level Lossless Sound Quality

48kHz sampling rate and 16-bit depth recording specifications can capture high-frequency audio signals, provide superior audio quality, ensure audio data integrity, and present rich delicate audio details, to meet the needs of professional audio recording.

Built-in Sound Card, Support Multi-scene Usage

High-performance audio processing sound card can capture the details of vocal voices, music, and other sounds, and optimize the sound to make it clearer and more natural. It can be used in live streaming, video shooting , podcasting and online meeting.

Innovative Duplex Transmission, Support Two-way Interaction and Monitoring

In mono mode, the microphone recording sound can be transmitted to the output device, and the background music and other audios from the phone/PC/tablet can also be transmitted to the microphone. Users can monitor the two-way transmitted sound in real-time through the microphone and adjust the recording effect in time.

Brand-new AI Denoise Technology, Support One-key Denoise

AI noise reduction algorithm automatically identifies environmental noise and eliminates it efficiently and accurately to obtain clear and pure audio. One-click operation quickly turns on/off the denoise function and easily copes with complicated environments.

Built-in Bluetooth 5.3 Chip, Support Bluetooth Input Audio

The receiver has a built-in Bluetooth chip of version 5.3, which can connect to a mobile phone to input audio signals stably and efficiently with low energy consumption. When shooting video or recording, users can input background music and other sound effects to enrich the recording.

Built-in DSP Chip, Provide Superior Reverb Effect 

The transmitter has a built-in DSP audio processing chip to optimize and reverberate the recording sound, enhance the stereo and spatial sense, and make the sound fuller and more real.

Digital/Analog Output, Universal for Camera, Smartphone, Computer

USB interface outputs high-fidelity, low-noise digital audio; 3.5mm interface automatically identify TRS/TRRS plugs and output analog audio. The two interfaces can output in sync and connect to cameras, mobile phones, and computers, making the sound pick-up more convenient and flexible.

Support Stepless Gain Control, One-key Muting and Mono/Stereo Mode

The output and monitoring gain can be adjusted to improve the microphone recording sensitivity without missing sound details. One-click muting can quickly respond to unexpected situations and avoid recording unnecessary sounds. Mono and stereo modes are supported to meet different recording needs.

Rechargeable Storage Case, Operating Time Up to 15 Hours

Microphones can be carried easily and charged automatically when stored inside the equipped charging case. The microphones' operation time is 7.5 hours. With the charging case, the total operation time reaches 15 hours, which is worry-free for long-term recording and outdoor use.

USB-C Charging Port, Support Charging While Using

Microphones can also be charged through the USB interface and support charging while using, which effectively avoids power shortage after a long time recording and affecting use.

Low Latency < 20ms, Working Range Up to 200m(Open Area)

With audio latency lower than 20ms, the wireless transmission is stable without breakpoints, achieving audio and video synchronization. The transmission distance is up to 200m(in an open area) and fully meets the needs of outdoor long-distance shooting and various shooting scenes.
