Description
The BOYA Mini 2-04 Wireless Microphone (TX-2, RX-1) is an ultra-compact dual-transmitter wireless microphone system designed for vloggers, interviewers, livestreamers, mobile journalists, online educators and modern content creators who want professional-quality audio from a lightweight setup. The system includes two super-mini transmitters and one USB-C receiver, making it ideal for two-person interviews, podcasts, collaborative videos and presentations. Each transmitter weighs only 5 grams, allowing it to sit discreetly on clothing without causing noticeable pulling or discomfort during long recording sessions.
Despite its extremely compact design, the BOYA Mini 2-04 delivers impressive audio performance with 48kHz/24-bit digital recording, a wide 20Hz–20kHz frequency response, 80dB signal-to-noise ratio and a maximum SPL of 120dB. These specifications help capture natural and detailed speech for YouTube videos, reels, tutorials, interviews, livestreaming and other voice-focused content.
A major highlight is BOYA’s True AI Noise Cancellation, powered by BOYA Intelligence. It offers Light and Strong noise-reduction modes, with Light mode reducing unwanted noise by up to -15dB and Strong mode reaching up to -40dB. This helps maintain clearer speech in environments affected by traffic, wind, keyboard noise, crowds and other background sounds.
The microphone system also supports Mono, Stereo and Safety Track output modes, together with an automatic limiter and -12dB Safety Track for additional protection against unexpected audio peaks. Wireless transmission reaches up to 100 meters in suitable open environments, while each transmitter provides at least 6 hours of battery life.
With BOYA Central app support, 6-level gain adjustment, EQ settings, monitoring and USB-C plug-and-play connectivity, the BOYA Mini 2-04 provides a powerful yet highly portable wireless audio solution for two-person mobile content creation.

True AI Noise Cancellation up to -40dB
The BOYA Mini 2-04 features advanced AI noise cancellation powered by BOYA Intelligence. The system has been developed to distinguish the human voice from unwanted environmental sounds and reduce distracting noise in real time. Users can select between Light and Strong noise cancellation modes depending on the recording environment. Light mode provides up to -15dB noise reduction while maintaining more natural ambient sound, whereas Strong mode reaches up to -40dB for challenging environments such as busy streets, crowded spaces or areas with machinery and other continuous background noise.
Dual 5g Super Mini Transmitters
The BOYA Mini 2-04 includes two transmitters, allowing two people to be recorded wirelessly at the same time. Each transmitter weighs only 5g, making it exceptionally lightweight and discreet when attached to a shirt, collar or jacket. This dual-microphone configuration makes the Mini 2-04 particularly useful for interviews, two-person podcasts, collaborative YouTube videos, presentations and other content where two speakers need their own microphone. The compact metal clip provides secure attachment while keeping the overall setup clean and professional.
48kHz / 24-bit High-Quality Audio
The BOYA Mini 2-04 captures audio at 48kHz sampling and 24-bit resolution, providing detailed digital sound suitable for professional and everyday content production. Its wide 20Hz–20kHz frequency response helps reproduce different vocal frequencies naturally, while an 80dB signal-to-noise ratio keeps electronic background noise under control. The microphone can also handle sound pressure levels of up to 120dB SPL, helping maintain cleaner recordings across both normal conversation and louder speaking situations.
Automatic Limiter & Safety Track
Unexpectedly loud speech or sudden sound peaks can cause clipping and distortion during recording. The BOYA Mini 2-04 includes an automatic limiter designed to help control those sudden peaks before they ruin an important take. It also supports a -12dB Safety Track, providing additional headroom for unpredictable volume changes. These features are especially useful for interviews, livestreaming, presentations and spontaneous video production where creators may not have time to constantly monitor recording levels.
Mono, Stereo & Safety Track Output
The microphone system offers Mono, Stereo and Safety Track output modes, giving creators greater flexibility over how two transmitters are recorded. Stereo mode can provide more separation between the two speakers for easier post-production, while Mono is convenient when a combined output is preferred. Safety Track adds extra protection against clipping, making the Mini 2-04 suitable for creators who want greater control over two-person recordings.
Up to 100m Wireless Transmission
BOYA Mini 2-04 provides wireless transmission at distances of up to 100 meters under suitable open and unobstructed conditions. This allows presenters, interview subjects and content creators to move freely while remaining connected to the recording device. The extended range is useful for outdoor vlogs, walking presentations, tutorials and other videos where the subject may need to move away from the smartphone or tablet. Actual range may vary depending on obstacles and wireless interference.
Up to 6 Hours Battery Life
Each Mini 2-04 transmitter contains a built-in 90mAh lithium-ion battery and delivers at least 6 hours of operating time on a full charge. This provides enough endurance for interviews, livestreams and multiple video shoots throughout the day. Unlike BOYA Mini 2 variants supplied with a charging case, the Mini 2-04 standard package does not include a charging case, so the microphones are charged using the supplied USB charging solution.
BOYA Central App Control
The BOYA Central app gives users additional control over the Mini 2-04 from a compatible smartphone. Available functions include 6-level gain adjustment, EQ customization and firmware updates, allowing creators to fine-tune microphone performance according to their voice and recording environment. This adds a useful level of customization to what is otherwise an extremely compact plug-and-play wireless microphone system.
USB-C Plug-and-Play Receiver
The included receiver uses USB-C connectivity and is designed for compatible smartphones, tablets and other USB-C devices. It is powered directly through the connected device, eliminating the need for a separate receiver battery. The receiver also supports gain control, monitoring and playback without requiring it to be disconnected, simplifying the recording and playback workflow for mobile content creators.
