Shure KSM9

The KSM9 is Shure's premier live vocal mic and with it's dual diaphragms can be switched between Cardioid and Supercardioid polar pattern modes.

As well as having a shock mount system to reduce handling noise, it also has a 3 stage grille to reduce pop and breath noise.

This microphone is highly regarded by live sound audio engineers due to it's feedback rejection, resistance to popping, quality of construction, and it's transparent sound.


  • Type: Condenser (Electret Biased)
  • Polar Pattern: Supercardioid and Cardioid
  • Frequency Response: 50Hz to 20kHz
  • Impedance: 150 Ohms
  • Maximum SPL: 152 dB
  • Applications: Live and recorded vocals
  • Power Requirements: 48v phantom power


Some owners compare this to the Shure Beta 87A and say the KSM9 has a clearer sound and has much less of a proximity effect. The positive reviews consistently talk about the overall quality of both its sound and construction, and its good handling of sibilance issues. Many reviewers also say this is a professional recording microphone.


As you may have guessed by its high Gearank score, we could not find any consistently reported negative issues with the KSM9.


If you're looking for a top-of-the-line microphone that will give you a transparent sound both on stage and in the studio then this is a great option for you. Get it and your sound guy or girl will thank you.

Although this was previously on our recommended list, and despite its high ratings, there are now more highly rated options available which you can see in our guide to The Best Live Vocal Mics - Handheld / Wired.
