Rank #8 in Best USB Microphone 2026: 10 Ranked, and Why the Big Numbers Lie
MAONO DGM20 RGB USB Condenser Microphone for PC
Price and rating as shown on Amazon when we collected them. Both change.
The MAONO GamerWave DGM20 is a USB condenser microphone that arrives with its own desk stand, pop filter, shock mount, boom adapter and a USB-C to USB-A/USB-C cable. It is listed at £28.49 and sits eighth in this guide, with 4.5 out of 5 from 1,120 ratings. The feature list is the usual gaming-mic set: nine RGB lighting modes, a mute button on top, a gain knob, and a one-touch noise reduction that switches on or off with a three-second press.
The number worth stopping on sits in the spec table, where the signal-to-noise ratio reads 73 and the audible noise figure reads 73 decibels — the same figure twice, one of four listings in this guide where those two fields match to the decibel exactly. The frequency response field says "20 KHz" on its own, which is a pitch at the very top of human hearing rather than anything a mic records, while the range is given separately as 50 Hz–20 kHz. There is a compatibility wobble too: the plug-and-play bullet carries a note beginning "Not compatible with XB", Xbox appears nowhere in the compatible devices field, and one of the reviews below reports the opposite for controllers. Everything on this page comes from the Amazon listing — we have not tested the microphone ourselves.

Questions people ask
Does the MAONO DGM20 have noise cancellation?
Yes. The listing describes a one-touch noise reduction function that is switched on or off by holding for three seconds, and the mic is sold as a noise cancellation condenser microphone.
What signal-to-noise ratio does the MAONO DGM20 have?
The spec table gives 73 for signal-to-noise ratio and 73 Decibels for audible noise, so both fields carry the same number.
Can I use the MAONO DGM20 with a games console?
The compatible devices field names Computer, PC, Laptop, Desktop, Mac OS, PS4 and PS5. The plug-and-play bullet carries a note that begins "Not compatible with XB" as the listing shows it, and Xbox is not named in any of the compatibility fields.
Does the MAONO DGM20 have a mute button and a gain control?
Yes. The listing describes a mute button on the top of the mic and a gain knob for checking whether your voice level is too high or too low.
What frequency response does the MAONO DGM20 have?
One field gives the frequency range as 50Hz-20KHz, while another lists "20 KHz" by itself — both are frequencies, not the sample rate some mic listings quote.
Does the MAONO DGM20 need batteries?
The specification table carries the line "Nonstandard Battery batteries required." All the listing says about power is that the microphone is corded electric and runs from USB.
