USB conference microphone for desktop use
The CMTECK CM-003 is a compact omnidirectional condenser microphone designed for computer-based communication. It connects via a 1.8 m USB cable and requires no driver installation on Windows or macOS systems. The unit weighs 0.318 kg and includes a mute button with LED status indicators. It is intended for users who need a simple plug-and-play audio capture device for calls, streaming or recording.
Omnidirectional pickup limited to 3 metre range
The microphone uses a dual-capsule design with a 360° polar pattern to capture sound equally from all directions. Its effective pickup distance is stated as 3 m, so participants seated farther away may not be heard clearly. The built-in CCS2.0 chip provides noise cancellation and echo reduction, but the device has no integrated speaker for audio playback. Compatibility excludes Raspberry Pi, Linux and Android platforms, limiting use to standard desktop operating systems.
Mute button with LED feedback decides suitability
A single hardware mute switch toggles between active and muted states, shown by a flashing green LED for working mode and a red LED for mute mode. This tactile control lets users silence the microphone instantly without software interaction. If a buyer requires physical mute confirmation and broad OS support without drivers, this specification makes the CM-003 the right part; those needing onboard monitoring or mobile device support should look elsewhere.

Questions about this item
Which model should I choose between the CM003 and the CM001 conference microphones?
The CM003 features a dual-capsule design with two omnidirectional capsules for a larger pickup range, while the CM001 is listed separately without those specifications.
What does the 45 decibel sensitivity mean for my recordings?
At 45 dB sensitivity the omnidirectional capsules capture clear voice up to 3 metres away, and the built-in CCS2.0 chip reduces background noise and echo during calls.
What does the USB 2.0 connection cap in practice?
The 1.8 metre USB 2.0 cable provides driver-free plug-and-play audio on Windows and macOS, but the device is not compatible with Raspberry Pi, Linux or Android systems.
