SF-940 Condenser Microphone Review / Test

Today I am reviewing the SF-940 mic. This is another one of those super cheap, mass produced, Chinese microphones that are sold under a plethora of different names. I think this is the last one on Amazon that I haven't reviewed, so if you come across any, make sure to send me a note letting me know!

What's In the Box 

  1. Microphone w/ 2-meter Cable Attached
  2. Microphone Stand

Performance / Features

The build quality on the microphone is sub par. It is full plastic construction, and it feels very week as though one drop or a tight squeeze with your hand might break it. The cable does feel relatively nice (compared to the rest of the mic). It is about 2x thicker than your typical iPhone charging cable, so it seems like it may last. The mic stand is a HUGE oversight. It is cheap plastic, and the worst part...the Microphone doesn't even fit in this mic stand; so it's useless.

There is an on/off switch on the front of the microphone which is kind of nice because it can be used as a Mute switch, but this feature also feels cheap and flimsy.

The frequency response is advertised as 50Hz - 16KHz which is respectable, and in all honesty it doesn't sound half bad for $13. However, the microphone is omnidirectional, regardless of the fact that it is marketed as a Noise Cancelling microphone. When testing this out, it offered little to no noise cancellation and it completely failed in this arena. 


  • Cheap
  • On/Off Switch
  • Decent Frequency Response


  • Poor Build Quality
  • Does not Perform as Advertised (fails at noise cancellation)
  • Microphone Stand is Non useable. 


I cannot recommend this microphone to anyone unless they are on a severely limited budget and want an omni-directional microphone. Instead of this, I would recommend saving up a few more dollars and investing in a higher quality microphone, or if this is your maximum budget, you can go with one of those Super Cheap PDMIC's. 

If you have any additional questions about this headset, leave them in the comments on this site or on the youtube channel, and I will try to reply ASAP.
