In-depth review of ONEKING Technology's core microphone products

ONEKING Technology's wireless microphone features an innovative three-microphone array design. The three pickup zones are arranged with their centers forming an equilateral triangle, and the lines connecting adjacent zones to the center of the triangle create 120° angles. This geometrically precise layout, combined with beamforming technology, enables directional sound capture within a specific angular range, effectively eliminating lateral noise while enhancing pickup distance and clarity.

Equipped with high-sensitivity digital microphone units, the device captures detailed sound across a broader frequency spectrum. Each pickup zone is backed by a professional digital microphone at its base, which collects speech and delivers premium audio capture through advanced processing algorithms. The integrated audio processor serves as the core computational unit, executing algorithms for echo cancellation, noise suppression, and beamforming.

Hardware Architecture:

• The device consists of a cover and a base shell forming an internal compartment.

• The cover incorporates three pickup zones.

• A PCB mainboard is mounted inside the compartment.

• Digital microphones are electrically connected to the PCB.

Audio Processing Chain:

• The audio processor is linked to a speech codec.

• The speech codec connects to a digital-to-analog converter (DAC).

• The DAC is coupled to an amplifier circuit.

User Interaction Design:

• Each pickup zone is accompanied by an indicator light.

• The cover includes a button panel with indicator lights for user control.

• A speaker grille is positioned at the center of the cover, with a speaker unit at the base.

In practical tests, the microphone demonstrated exceptional directional pickup performance. When the speaker was positioned directly in front of the device, high speech clarity was maintained even in noisy environments (e.g., air conditioning, keyboard sounds). Tests revealed a speech intelligibility rate exceeding 95% at distances up to 5 meters, significantly outperforming traditional conference microphones. The echo cancellation algorithm effectively prevented reverberation issues common in remote meetings, enabling natural two-way communication.

The microphone supports multiple connection options, including USB and a 3.5mm audio interface, and is compatible with Windows, Mac, Android, and other operating systems. Its built-in rechargeable battery provides up to 8 hours of continuous operation, meeting the demands of all-day meetings.

ONEKING's microphone represents another pinnacle of its audio technology. The product achieves 360° omnidirectional pickup within a 5-meter radius, featuring adaptive voice gain control that ensures consistent audio quality regardless of distance—delivering uniform performance for both near and far-field capture.

Powered by a deep learning-based AI noise reduction algorithm, it effectively eliminates over 300 types of common noises—including desk taps, keyboard clicks, screen touches, air conditioning, and fan sounds—while reducing environmental reverberation to maintain crystal-clear voice transmission. During testing, the microphone consistently identified and suppressed simulated noises such as typing, AC operation, and paper rustling, all while preserving the integrity of speech signals.

Broad Compatibility:

• USB connectivity for seamless integration with multiple operating systems

• Ideal for conferences, training sessions, recorded lectures, and educational environments

The microphone’s bottom features a hidden cable interface design, ensuring stable connections while maintaining a clean desktop aesthetic. It supports flexible mounting options—on desks, tripods, or ceiling mounts—adapting effortlessly to diverse installation environments. This versatility makes it suitable for deployment in various meeting spaces.

For system integration, the microphone enables distributed solutions such as conference all-in-one displays paired with microphone arrays. This capability is particularly valuable for mid-to-large meeting rooms and training classrooms, where multiple microphones can collaborate to achieve uniform pickup and playback across the entire space.

Audio Processing Algorithms and Technical Advantages
The core competitiveness of ONEKING Technology's microphone products stems from its advanced audio processing algorithms and profound technical expertise. The company has mastered a comprehensive suite of audio technologies, including echo cancellation, far-field pickup, beamforming, and background noise reduction, making it one of the few enterprises in China with genuine proprietary audio intellectual property.

Echo Cancellation Technology
ONEKING's echo cancellation algorithm effectively distinguishes between voice signals and echo signals. Using adaptive filters, it eliminates echoes while ensuring speech clarity. This technology is particularly critical in video conferencing scenarios, preventing echoes caused by speaker output being recaptured by the microphone.

Beamforming Technology
Leveraging microphone array-based beamforming, the device directionally captures sound from specific directions while suppressing noise interference from other angles. ONEKING employs advanced beamforming algorithms to accurately identify sound source locations and form directional pickup beams, significantly improving the signal-to-noise ratio.

Noise Suppression Technology
Through deep learning algorithms, ONEKING's microphones can identify and suppress various common environmental noises, such as keyboard clicks, air conditioning sounds, and fan noises. Trained on extensive noise samples, the system distinguishes between speech and noise in real time, preserving voice signals while suppressing unwanted noise components.

Full-Duplex Communication Technology
ONEKING's products support full-duplex voice communication, enabling simultaneous transmission and reception without interruptions or voice clipping. This ensures natural and fluid conversations, enhancing the overall user experience.
