The BOYA K9 is a professional USB condenser microphone designed for streaming, podcasting, gaming, voice recording, online meetings, and content creation. It combines 48 kHz / 24-bit audio, three selectable polar patterns, one-tap noise cancellation, RGB lighting, real-time monitoring, and convenient gain control in a desktop microphone setup.
With its supercardioid, omnidirectional, and bidirectional pickup modes, the K9 can adapt to solo recording, group conversations, interviews, and streaming setups. Its USB-C connection provides plug-and-play operation with compatible computers and phones.
The BOYA K9 supports 48 kHz sampling and 16-bit/24-bit bit depth, providing detailed digital audio for vocals, podcasts, gaming, streaming, meetings, and other voice-recording applications.
The K9 offers three selectable pickup patterns:
This flexibility allows the microphone to be adjusted according to the recording situation.
The BOYA K9 features built-in noise cancellation that can be activated by pressing and holding the top of the microphone. This helps reduce unwanted ambient noise during recordings and streams.
The K9 includes integrated RGB lighting with static, cycle, and gradient effects. These lighting modes make the microphone suitable for gaming setups, streaming desks, podcasts, and modern content-creation environments.
A 3.5mm headphone output allows you to monitor your microphone audio in real time. This is useful for checking voice levels and audio quality while recording or streaming.
The physical gain knob provides a 0–27 dB adjustment range, allowing you to increase or decrease microphone volume directly from the microphone without relying entirely on software controls.
The included shock mount helps isolate the microphone from unwanted mechanical vibrations, while the pop filter helps reduce unwanted plosive sounds when speaking close to the microphone.
The BOYA K9 uses USB-C audio output and includes a 1.8m USB-C to USB-C / USB-A cable. It is designed for straightforward connection to compatible computers and phones without requiring dedicated drivers.
