Sound Quality and Features
The Sennheiser MD421 Kompakt, a smaller version of the legendary MD421, retains the warmth, clarity, and punch synonymous with its predecessor. It delivers a rich, focused sound, particularly excelling in capturing the mid-range frequencies crucial for toms. The cardioid polar pattern minimizes bleed, ensuring a clean and precise recording.

This compact microphone offers a significant advantage in terms of placement. Its smaller size allows for closer miking without obstructing drum access. The included rim mount adds to its practicality and stability during performances.
Performance in a Drum Setting
In my drum recording setup, I used three MD421 Kompakts for snare, toms, and floor tom. The mics delivered a powerful, punchy sound with excellent mid-range presence that enhances the character of the drums. The sound profile is suitably beefy for live shows.

Compared to other popular tom microphones, the MD421 Kompakt provides an especially strong mid-to-low end response, adding depth and definition. Its cardioid pattern efficiently reduces unwanted bleed from other instruments in the kit.

Build Quality and Practicality
The build quality is surprisingly robust for its compact form. Although smaller than the original MD421, it still feels durable and capable of handling the rigors of studio and live use.

While the included rim mount is a welcome addition, it initially lacked sufficient tightness. A minor adjustment with a screwdriver solved this issue, ensuring stability during playing. The size, while compact, is still larger than some other tom microphones like the Sennheiser e604 or the Audix i5.

Price and Value
The MD421 Kompakt commands a premium price tag, a significant investment for a single dynamic microphone. However, its versatility and ability to perform well in diverse applications make it a sound choice.

While pricier than options like the Sennheiser e604 or the Audix i5, its superior performance and adaptability in different recording contexts justify the higher cost for those seeking a versatile microphone.
Conclusion
The Sennheiser MD421 Kompakt is a high-quality, versatile microphone that delivers excellent sound and performance. Its compact size makes it ideal for close miking on drums without intruding on playing space. While the price is higher than some competitors, its versatility and robust build quality justify the cost for musicians requiring a dynamic microphone for various applications.
However, if specific tom miking is the sole requirement, and budget is a constraint, the Sennheiser e604 or similar budget-friendly options might be more suitable. The MD421 Kompakt shines as a versatile workhorse, delivering superior performance across various instruments and applications.
