Sennheiser MK4 Mic Review / Test

Today we're looking at the Sennheiser MK4 XLR Condenser Microphone, which is a great way to get into the Sennheiser / Neumann condenser mic ecosystem. 

For this review, I have the mic connected directly to the Focusrite Scarlett 2i2 2nd gen, with the gain set at 11:00. I have done no post processing on the audio, it is all raw, but the audio was slightly boosted in final cut pro X to simply make the audio easier to listen to.

Performance / Features

The build quality of this mic is good. I'm legitimately running out of things to say about all these mics. Most of them have an all metal body and a metal grill. This mic is no different. It has no switches for a padding or high pass / low pass, but on the bottom you'll find an XLR port. 

The frequency response is listed as 20Hz - 20kHz. This has a minor roll off beginning at 150Hz, and a much more drastic roll off beginning at 50Hz. The low-mids are flat until you hit 1kHz and it boosts 1dB with the peak at 1.5kHz which then returns to flat at 2.5kHz where it begins it's presence/treble/air boost beginning at 2.75kHz and ranging all the way up to 10kHz, where it gradually rolls off the air, where it is neutral at ~14kHz.

The overall performance of this mic is great for the price. On electric guitar, this mic sounds a bit dull because it's not over boosted anywhere, but I think fo that as a good thing when recording. On acoustic it sounded stellar with a good body and plenty of shimmer on the top. For singing it had a nice and airy tone, and on spoken word it had plenty of clarity that could be offset beautifully while utilizing the proximity effect. Additionally the off axis coloration around 90-degrees is not unpleasant like many cheaper condensers, which will yield a much better sounding recording if you're in a reverberant room. 


  • Nice, fairly subtle coloration

  • Good off axis coloration

  • Pretty hot output signal

  • Decent job at background noise rejection

  • Respectable 10dBA self noise

  • Good built quality


  • I personally don't like the look of it.


This seems to be a great all purpose microphone as it worked well on everything I tested it on. I think where it really shines is on voice over. The thing I have loved about the Neumann condensers I have tested is the proximity effect. This microphone offers that buttery smooth low end that helps off set the boosts to the presence/treble/air, and it sounds stellar for that considering the price. 

If you have any additional questions about this microphone, leave them on the youtube video, and I will try to reply ASAP.
