Neumann KMS 105 Review

When it comes to professional audio equipment, Neumann is a name synonymous with excellence. For decades, the German manufacturer has set the standard for microphones used in studios and live performances worldwide. Among their impressive lineup, the Neumann KMS 105 stands out as a flagship vocal microphone designed for live stage use. Whether you’re a singer, sound engineer, or audiophile, the KMS 105 promises to deliver pristine sound reproduction with the kind of reliability that Neumann is known for. In this review, we’ll explore every facet of the KMS 105—its design, technical prowess, real-world performance, and how it stacks up against competitors—to determine if it truly lives up to its reputation.

The Neumann KMS 105 is a handheld condenser microphone tailored specifically for live vocal performances. Introduced as part of the KMS (Kondensator-Mikrofon-Serie) line, it combines the clarity and nuance of a studio condenser with the ruggedness required for the stage. Available in two finishes—matte black and nickel—it exudes a sleek, professional aesthetic that immediately signals quality.

Out of the box, the KMS 105 feels substantial yet comfortable to hold. Weighing in at approximately 300 grams (10.5 ounces), it strikes a balance between durability and ergonomics. The microphone comes packaged with a padded nylon pouch and a microphone clip, though many users might opt for a higher-quality stand or shock mount for serious gigs. Its build quality is impeccable, with a solid metal housing that inspires confidence in its ability to withstand the rigors of touring.

What sets the KMS 105 apart from many stage microphones is its supercardioid polar pattern, a feature that promises excellent feedback rejection and focused sound capture. But does it deliver on this promise? Let’s dive deeper into its design and specifications to find out.

Design and Build Quality

Neumann’s attention to detail is evident in the KMS 105’s construction. The microphone features a hardened steel grille that protects the capsule while minimizing pop noises and wind interference—a critical consideration for vocalists performing up close. The grille is removable for cleaning, which is a thoughtful touch for long-term maintenance.

The capsule itself is a key highlight. Derived from Neumann’s acclaimed K 50 condenser capsule (also found in the studio-grade KMS 150), it’s engineered to capture the full spectrum of the human voice with remarkable fidelity. The microphone’s internal design includes a multi-layer acoustic filter to reduce plosives and sibilance, ensuring that “p” and “s” sounds don’t overwhelm the mix.

At 180 mm (7 inches) in length, the KMS 105 is slightly longer than some competitors like the Shure SM58, but its slim profile makes it easy to grip. The matte finish not only looks elegant but also resists fingerprints and wear over time. Phantom power (48V) is required to operate the condenser capsule, which is standard for high-end vocal mics but worth noting for those upgrading from dynamic microphones.

Technical Specifications

To understand the KMS 105’s capabilities, let’s break down its key specs:

Polar Pattern: Supercardioid
Frequency Response: 20 Hz to 20 kHz
Sensitivity: 4.5 mV/Pa
Maximum SPL: 150 dB
Self-Noise: 18 dB-A
Impedance: 50 ohms
Power Requirement: 48V phantom power
Connector: XLR 3-pin

The supercardioid pattern is tighter than a typical cardioid, offering superior off-axis rejection. This makes it ideal for noisy stages where monitors and instruments could otherwise bleed into the mic. The frequency response is exceptionally flat, with a gentle presence boost around 4-5 kHz to enhance vocal clarity without sounding harsh.

With a maximum sound pressure level (SPL) of 150 dB, the KMS 105 can handle even the loudest vocalists without distortion—a feat many dynamic mics struggle to match. Its low self-noise (18 dB-A) ensures that quiet passages remain clean, a testament to Neumann’s engineering prowess

Sound Quality: The Neumann Signature

The true test of any microphone is how it sounds, and the KMS 105 does not disappoint. In testing, it delivers the warm, detailed sound that Neumann is famous for, with a transparency that captures every nuance of the voice. Whether you’re a soft crooner or a belting rock singer, this mic adapts effortlessly.

The low-end response is smooth and controlled, avoiding the muddiness that can plague lesser microphones. Mids are rich and natural, giving vocals a lifelike quality that sits beautifully in a mix. The presence boost in the upper mids adds articulation, making lyrics intelligible even in dense arrangements. High frequencies are crisp yet never sibilant, thanks to the internal pop filtering.

One standout feature is the mic’s ability to reject feedback. On a live stage with monitors positioned close to the vocalist, the supercardioid pattern shines, isolating the voice and minimizing unwanted pickup. This makes it a favorite for front-of-house engineers who need reliability in challenging acoustic environments.

Performance in Different Scenarios

To fully evaluate the KMS 105, let’s consider its performance across various use cases:

Live Vocals: This is where the KMS 105 excels. Its clarity and feedback rejection make it a top choice for professional singers in venues of all sizes. From intimate acoustic sets to stadium rock shows, it consistently delivers studio-quality sound. The high SPL handling also means it can keep up with powerful vocalists without clipping.
Studio Recording: While designed for live use, the KMS 105 holds its own in the studio. Its detailed capture rivals many dedicated studio condensers, making it a versatile tool for recording vocals, voiceovers, or even acoustic instruments in a pinch.
Speech and Presentation: For spoken word applications like lectures or podcasts, the KMS 105 offers exceptional intelligibility. The presence boost ensures every word is clear, though its price point might deter casual users from choosing it over a dedicated speech mic.
Noisy Environments: In settings with significant background noise—think outdoor festivals or busy convention halls—the supercardioid pattern proves its worth, keeping the focus on the voice and reducing ambient pickup.

Pros and Cons

No product is perfect, so let’s weigh the strengths and weaknesses of the KMS 105.

Pros:

Outstanding sound quality with a natural, detailed vocal reproduction
Excellent feedback rejection due to the supercardioid pattern
High SPL handling for loud performers
Robust, premium build quality
Versatile for both live and studio use

Cons:

Requires phantom power, which may complicate setups for beginners
Premium price tag (typically $700-$800) puts it out of reach for budget-conscious users
Slightly longer and heavier than some handheld alternatives

Comparisons with Competitors

To put the KMS 105 in context, let’s compare it to a few popular alternatives:

Shure SM58: The industry-standard dynamic mic is rugged and affordable ($99), but it lacks the KMS 105’s clarity and frequency range. The SM58 is a workhorse; the KMS 105 is a precision instrument.
Sennheiser e965: Another high-end condenser, the e965 ($500-$600) offers switchable cardioid/supercardioid patterns and a slightly warmer tone. The KMS 105 edges it out in feedback rejection and transparency, though the e965’s versatility is a strong selling point.
AKG C7: Priced similarly to the KMS 105, the C7 ($250-$300) is a solid condenser with good feedback resistance. However, it doesn’t match the Neumann’s build quality or sonic refinement.
Neumann KMS 104: The KMS 104, with its cardioid pattern, is a sibling to the 105. It’s better suited for quieter stages but sacrifices some off-axis rejection. The choice between them depends on your specific needs.

The KMS 105 stands tall in this company, justifying its premium status with unmatched sound and reliability.

Conclusion

The Neumann KMS 105 is a triumph of audio engineering—a microphone that brings studio-grade performance to the live stage. Its combination of pristine sound, robust design, and feedback rejection makes it a standout in a crowded market. While its cost and power requirements may deter some, those who value quality above all else will find it worth every penny.

For singers who want their voice to shine and engineers who need a reliable tool, the KMS 105 delivers in spades. It’s not just a microphone; it’s a statement of intent—a commitment to excellence that echoes Neumann’s legacy. If you’re ready to elevate your live sound, the KMS 105 is ready to take you there.
