The Sennheiser HSP 2-ew-3 is an ultra-lightweight omnidirectional condenser neckband microphone with patented sweat-protected Umbrella Diaphragm, 1.1 mm adjustable boom, and modular design for hands-free vocal/speech applications. It delivers 20 Hz–20 kHz response, 150 dB max SPL, and includes a hard case—ideal for theater, broadcast, and fitness.
The Sennheiser HSP 2-ew-3 is a professional-grade headworn condenser microphone engineered for demanding “hands-free” vocal and speech scenarios, featuring a permanently polarized MKE platinum capsule with true omnidirectional pickup (360° uniform sensitivity) to capture natural voice timbre from any head position without proximity effect. A hydrophobic membrane overlay—shields the transducer from sweat and moisture (IPX4-equivalent), ensuring reliability during intense performances, fitness instruction, or outdoor broadcasts. The ultra-thin 1.1 mm boom arm (twist-proof, left/right mountable) adjusts in length and angle via a flexible gooseneck, while the lightweight neckband (<20 g total) conforms to all head sizes with soft, hypoallergenic padding and stays clear of clothing for unobtrusive placement. Modular snap-on cables (1.6 m, locking 3.5 mm mini-jack) support Sennheiser evolution wireless, 3000/5000 series, or stripped/tinned leads, with all metal components protected by physical vapor deposition (PVD) for corrosion resistance. Delivering a wide 20 Hz–20 kHz frequency response (±3 dB), 28 dB-A signal-to-noise ratio, and 150 dB max SPL, it excels in high-SPL environments with low self-noise. Compatible with the cardioid HSP 4 boom for directional flexibility, the HSP 2-ew-3 includes a hard carrying case and is available in black or beige for aesthetic integration.
