Sennheiser MK-4 Overview

From Manufacturer

Designed with an emphasis on sound quality over bells and whistles, the Sennheiser MK 4 is a large-diaphragm true condenser microphone offering warm and detailed audio capture that complements a range of sources from vocals and speech to acoustic instruments, drum overheads, guitar amps, and more. Since it incorporates an internally shock-mounted capsule and a rugged metal housing, the MK 4 is not only an obvious choice for the studio, but also a dependable companion on stage.

The MK 4 features a large 1" diaphragm plated in 24kt gold to enhance conductivity, resist corrosion, and yield a tone based on the e 965 vocal mic. The cardioid polar pattern strongly rejects sound behind the mic while picking up side-entry sound without coloration. The mic's low-noise circuitry further solidifies it as a studio mic capable of meeting the demands of digital recording systems. Use an XLR mic cable (available separately) to connect the MK 4 to any mic preamp that can supply 48V phantom power.

Versatility Is King
From acoustic guitars to vocals and even drum overheads, the MK 4's frequency response has been tailored to ensure a natural reproduction of the sound source, making it ideal for any home or project studio. It's ability to accurately reproduce such a wide range of sounds is thanks mostly in part to its 1" true condenser capsule, which is based on the acoustics of the e 965 high-end vocal mic. No frills, no gimmicks. Just solid engineering and an elegant design.
True Condenser Capsule
The MK 4 features a 24kt gold-sputtered diaphragm at the heart of its 1" true condenser capsule. Gold is an excellent conductor for electrical signals and also prevents corrosion over time. Factor in the cardioid polar pattern and you've got a single microphone that's ready to record anything you put in front it.
Cardioid Polar Pattern
The finest sound structures are well resolved, while sound coming from the sides is picked up without coloration, which means that it does not alter the overall sound quality. Furthermore, the microphone has a very harmonious presence, featuring vivid mids and is also highly detailed in the bass range. At the same time, typical cardioid cancellation is relatively frequency-independent, which is unusual for a large-diaphragm mic.
Sturdily Built
Despite its detailed and fine studio sound, the MK 4 mic is an incredibly rugged tool. The compact electronics, superior materials, and zinc die-cast casing ensure that the MK 4 is the perfect partner for rough recording environments.

Sennheiser MK-4 Reviews

Plain design, excellent sound!

By TK

I have tried the RE-20, MKH 416, and a few others but have come back to my first love, the MK4. It has a simple design (some call it unattractive), excellent build quality, and very low self noise. The sound is great just plugged directly into my Scarlett Solo 4th Gen, but then really comes to life when I add a mic-pre into the mix. The proximity effect is silky smooth and “broadcasty.” Keep in mind that this is made in Germany, and that Sennheiser owns Neumann. I feel that there are some pronounced similarities with the Neumann microphones that hover around the $1000 mark. Overall, this is an excellent value if it’s compatible with your vocal characteristics.

This microphone picks up every piece of my voice and with great detail. The quality of the microphone is superb and top-of-the-line. The only drawback is the appearance, I'm not really a fan of the gray. Regardless, it's a tremendous microphone and a great purchase on my part.
