Designed for professional broadcast, theatre, house of worship, and conferencing environments, the 4466 CORE+ headset integrates DPA's 5 mm pre-polarized condenser capsule with advanced CORE+ by DPA signal processing. The omnidirectional polar pattern provides consistent off-axis response while maintaining clean reproduction across the full 20 Hz to 20 kHz range. With 6 mV/Pa sensitivity matched to typical wireless transmitter inputs, this headset eliminates gain staging guesswork and delivers reliable signal levels whether the talent is speaking or singing.

The Red Dot award-winning dual-ear frame accommodates all head sizes through its adjustable three-point grip system, which secures the mic above, below, and behind the ear. Boom length and capsule placement adjust independently, while a 90° rotating cable guide keeps the 1.3 m cable discreetly routed away from camera sightlines. The non-reflective PVD coating on the frame, boom, and capsule housing eliminates glare under stage lighting and studio fixtures.

The IP58-rated capsule withstands exposure to moisture and dust, making this headset suitable for outdoor festivals, humid worship spaces, and demanding theatrical productions. Maximum SPL handling reaches 144 dB peak at 10% THD, allowing engineers to push input levels without audible distortion even during dynamic vocal performances.
