When it comes to high-end microphones, Neumann is a name that commands respect. Known for its studio-grade condenser microphones, the German manufacturer has a storied history of delivering exceptional audio quality. The Neumann KMS 105, a handheld vocal microphone designed primarily for live performance, carries this legacy into the stage environment. With its sleek design, advanced engineering, and pristine sound reproduction, the KMS 105 has become a favorite among vocalists and audio professionals. But does it live up to the hype? In this in-depth review, we’ll explore every facet of the Neumann KMS 105, from its build quality to its real-world performance, to help you decide if it’s the right tool for your needs.

Overview and First Impressions

The Neumann KMS 105 is a supercardioid condenser microphone tailored for live vocal applications. Introduced as part of Neumann’s KMS (Kondensator-Mikrofon-Serie) lineup, it sits alongside models like the KMS 104 (cardioid) and KMS 104 Plus (cardioid with enhanced low-end response). The KMS 105, however, stands out with its supercardioid polar pattern, which offers superior off-axis rejection—a critical feature for noisy stage environments.

Out of the box, the KMS 105 exudes quality. It arrives in a padded carrying pouch with a microphone clip, and its nickel or matte black finish (depending on the variant) gives it a premium, professional aesthetic. Weighing just 300 grams (10.6 ounces) and measuring 180 mm in length, it’s lightweight and ergonomic, making it comfortable for extended performances. The all-metal construction feels robust, suggesting it can withstand the rigors of touring, yet it retains an elegant simplicity that aligns with Neumann’s brand identity.

Design and Build Quality

The KMS 105’s design is a blend of form and function. Its cylindrical body is crafted from high-quality steel, ensuring durability without excessive weight. The microphone grille, a multilayered acoustic filter, protects the capsule while minimizing plosives and wind noise—common challenges in live settings. This grille is removable for cleaning, a thoughtful touch for performers who rely on their gear night after night.

Underneath the grille lies Neumann’s KK 105 capsule, a key component derived from the company’s acclaimed K 50 studio capsule. This condenser element is optimized for close-up vocal use, delivering the clarity and detail Neumann is known for. The microphone requires 48V phantom power, standard for condenser mics, and connects via a balanced XLR output.

One standout design feature is the integrated pop filter. Unlike many handheld mics that rely on external windscreens, the KMS 105 incorporates acoustic filtering directly into its structure. This reduces the need for additional accessories, streamlining setup for live sound engineers. Additionally, the mic’s low self-noise (18 dB-A) and high maximum SPL (150 dB) make it versatile across a range of vocal styles, from soft crooning to powerful belting.

Technical Specifications

To understand the KMS 105’s capabilities, let’s dive into its technical specs:

• Transducer Type: Condenser
• Polar Pattern: Supercardioid
• Frequency Response: 20 Hz – 20 kHz
• Sensitivity: 4.5 mV/Pa (-47 dBV)
• Equivalent Noise Level: 18 dB-A
• Maximum SPL: 150 dB (at 0.5% THD)
• Impedance: 50 ohms
• Power Requirement: 48V phantom power (±4V)
• Weight: 300 g (10.6 oz)
• Dimensions: 180 mm (L) x 48 mm (D)

The frequency response is notably flat across the vocal range, with a gentle presence boost around 4-5 kHz to enhance clarity and articulation. This tailored response ensures vocals cut through dense mixes without sounding harsh. The supercardioid pattern provides a tighter pickup area than a cardioid mic, rejecting sound from the sides and rear more effectively—a boon for stages with loud monitors or multiple performers.

Sound Quality

The true test of any microphone is its sound, and the KMS 105 delivers in spades. Its condenser capsule captures vocals with remarkable transparency, preserving nuances that dynamic mics often miss. Singers with dynamic ranges will appreciate how the KMS 105 handles both delicate passages and soaring highs without distortion, thanks to its high SPL handling.

In testing, the microphone excels at reproducing the human voice with a natural, uncolored tone. The presence boost adds intelligibility, making lyrics stand out even in challenging acoustic environments. Compared to dynamic mics like the Shure SM58, the KMS 105 offers greater detail and a wider frequency response, though it lacks the rugged simplicity that makes the SM58 a workhorse.

The supercardioid pattern shines in live settings. During a simulated stage test with monitor wedges placed close to the mic, feedback was minimal, even at high gain levels. This rejection capability is a game-changer for performers who need to move freely without worrying about unwanted noise creeping into the mix.

However, the KMS 105 isn’t without quirks. Its sensitivity to plosives, while mitigated by the internal pop filter, can still be noticeable with certain vocal techniques. Singers who emphasize “p” and “b” sounds may need to adjust their mic position slightly. Additionally, its condenser nature makes it more susceptible to handling noise than dynamic alternatives, so a steady grip or shock-mounted stand is recommended.

Applications

The KMS 105 is marketed as a live vocal mic, and that’s where it truly shines. It’s ideal for:

• Concert Performances: Soloists and lead vocalists benefit from its clarity and feedback resistance, especially in venues with complex monitor setups.
• Theater and Spoken Word: The mic’s articulate sound reproduction suits musical theater and public speaking, where every word matters.
• Studio Recording: While not its primary purpose, the KMS 105 can double as a studio mic for vocalists who prefer its live-oriented sound.

It’s less suited for high-SPL sources like drums or guitar amps, where its condenser design could overload. For vocalists in extremely loud environments (e.g., heavy metal concerts), a dynamic mic might be more practical due to its durability and lower sensitivity.

Strengths

1. Exceptional Sound Quality: The KMS 105 offers studio-grade audio in a live package, with a transparent, detailed sound that elevates vocal performances.
2. Feedback Rejection: The supercardioid pattern and thoughtful engineering minimize feedback, even in monitor-heavy setups.
3. Build Quality: Its robust yet lightweight construction ensures longevity without sacrificing comfort.
4. Versatility: While optimized for live vocals, it’s adaptable for studio use or spoken-word applications.

Weaknesses

1. Price: At around $700-$800 (as of March 2025), the KMS 105 is a significant investment compared to dynamic mics like the Shure SM58 ($100) or Sennheiser e945 ($200).
2. Fragility: As a condenser mic, it’s less rugged than dynamic options, requiring careful handling and phantom power.
3. Handling Noise: Without a shock mount, slight hand movements can translate into audible noise.

Comparisons with Competitors

To contextualize the KMS 105, let’s compare it to two popular alternatives:

• Shure Beta 87A ($250): Another supercardioid condenser mic, the Beta 87A is a direct competitor. It offers similar feedback rejection and a bright vocal tone but lacks the KMS 105’s nuanced detail and flatter frequency response. The Shure is also slightly cheaper and more rugged, appealing to budget-conscious touring artists.
• Sennheiser e965 ($500): This dual-pattern (cardioid/supercardioid) condenser mic rivals the KMS 105 in sound quality and build. The e965’s switchable polar pattern adds flexibility, but its slightly warmer tone contrasts with the Neumann’s neutrality. Price-wise, it’s more affordable, though it doesn’t carry Neumann’s prestige.

The KMS 105 edges out both in terms of sonic purity and brand cachet, but its higher cost and condenser-specific needs may deter some users.

Real-World Performance

In a live setting—say, a mid-sized venue with a full band—the KMS 105 proves its worth. A vocalist performing a mix of ballads and uptempo tracks would notice how the mic captures every breath and inflection, projecting them clearly over the instrumentation. Sound engineers appreciate the minimal EQ tweaking required; the mic’s natural response often sounds “right” straight out of the gate.

In a studio test, recording a vocal track with the KMS 105 yields results comparable to entry-level Neumann studio mics like the TLM 102. While it lacks the full-bodied warmth of larger-diaphragm models, its clarity suits modern pop and acoustic genres.

Who Should Buy the Neumann KMS 105?

The KMS 105 is best suited for:

• Professional vocalists who prioritize sound quality and perform in controlled live environments.
• Audio engineers seeking a high-end handheld mic for live sound reinforcement.
• Artists willing to invest in premium gear for a competitive edge.

It’s less ideal for beginners, budget-conscious performers, or those in rough-and-tumble gigging scenarios where a dynamic mic might suffice.
