Neumann has officially announced the KK 104 A and KK 105 A, a new generation of premium condenser capsule heads designed for Sennheiser wireless handheld transmitters.
Succeeding the popular KK 204 and KK 205 models, the new A-Series capsules bring the detail, transient speed, and transparency of Neumann’s KMS studio-stage condensers to Sennheiser’s latest digital wireless platforms—including the new Spectera ecosystem, EW-D, EW-DX, and Digital 6000/9000 systems.
Both capsules are designed to tackle high-SPL stage environments while delivering high gain-before-feedback, reduced handling noise, and minimal proximity effect thanks to a built-in fixed low-cut filter.
Polar Pattern Options: Cardioid vs. Supercardioid
- KK 104 A (Cardioid): Features a balanced cardioid pickup pattern for excellent feedback rejection alongside greater freedom of movement for vocalists who move around the stage.
- KK 105 A (Supercardioid): Uses a tighter supercardioid pattern to provide maximum off-axis rejection and isolation, making it ideal for loud, crowded stages and tight in-ear monitoring environments.

Key Technical Features & Upgrades
- Native Compatibility: Operates directly with Sennheiser Spectera, EW-D, EW-DX, and Digital 6000/9000 handheld transmitters.
- True Condenser Performance: Offers fast transient response, natural vocal detail, and high SPL handling capability.
- Integrated Protection: Hardened steel grille with internal pop shield to handle plosives, sibilance, and moisture.
- Acoustical Decoupling: Internal shock-mounting system lowers handling noise on stage.
- Finishes: Available in classic Matte Nickel and Black.
“The KK 204 and KK 205 set a new standard for wireless vocal performance… With the KK 104 A and KK 105 A, we’ve pushed that concept even further. These new capsule heads are optimized for today’s wireless workflows while preserving the unmistakable Neumann character that artists and engineers trust.”
— Stephan Mauer, Director Product Management at Neumann
Availability
First showcased at IBC 2026 alongside the Sennheiser Spectera SKM transmitter, the Neumann KK 104 A and KK 105 A capsule heads are scheduled for global shipping in late September 2026.
