Sennheiser MK 4 Cardioid Condenser Microphone

The MK 4 is Sennheiser's large-diaphragm cardioid condenser for home, project, and professional studios, built around a 1-inch true condenser capsule that delivers a warm, powerful sound on vocals, acoustic guitar, piano, and amp cabinets. Its cardioid pattern focuses on the source in front of the mic while rejecting off-axis room sound and spill, which keeps a home or project studio recording clean without expensive room treatment. A 20 Hz to 20,000 Hz frequency response captures the full detail of a performance from low warmth to airy top end.

A low 10 dB(A) self-noise floor means the MK 4 stays quiet on delicate acoustic sources and whispered vocal takes where a noisier capsule would show its hand. The rugged housing and internal shock decoupling keep it stable on a stand without picking up handling or floor vibration, and it ships ready to mount with a standard microphone clip. It requires standard P48 phantom power from an interface, mixer, or preamp and connects over a 3-pin XLR, making it a straightforward drop-in for a first serious studio microphone or a reliable workhorse in a larger space.
