The Sennheiser HSP 2-3 is a professional, high-quality headset microphone designed for hands-free use with Sennheiser 2000, 3000, and 5000 series transmitters. Featuring a spherical omnidirectional microphone, ultra-thin adjustable boom and comfortable, discreet headband, it delivers natural sound with excellent intelligibility for live performances, theater, musicals, and broadcast applications.
The Sennheiser HSP 2-3 headset microphone offers professional-grade audio performance in an ergonomic, virtually invisible design. Engineered for hands-free applications, it is ideal for live vocals, theater, musicals, broadcast, and spoken word performances. The headset features a spherical (omnidirectional) microphone with the patented Umbrella Diaphragm™ membrane, providing exceptional protection against sweat and moisture while maintaining crystal-clear sound.
The adjustable ultra-thin boom (1.1 mm) allows precise placement on either side of the head, and the headband is designed for comfort across a variety of head sizes. Its neckband keeps the microphone away from collars and clothing, reducing handling and clothing noise. The replaceable cable and metal components with protective vapor-deposited coating ensure durability for daily professional use.
With its small 4.8 mm microphone diameter, low-noise condenser capsule, and high maximum acoustic pressure handling up to 150 dB, the HSP 2-3 is versatile enough for demanding stage and live applications while remaining unobtrusive.
