Overview

The Sennheiser 508245 is a professional-grade wireless headset microphone built around the newly developed KE 4 omnidirectional condenser capsule. This pre-polarized element is engineered to capture voice with warm, detailed nuances and distortion-free reproduction, making it a strong choice for live presentations, fitness instruction, house-of-worship speaking, and theatrical performance. The flexible, ergonomic neckband wraps securely around the head and holds the boom-mounted capsule in a consistent position near the mouth, ensuring stable audio even during vigorous movement.

Durability is a key design focus. Sennheiser's patented umbrella diaphragm and rubber sealing ring protect the capsule from moisture, making the 508245 genuinely sweat-resistant rather than merely splash-proof. The allergy-friendly coating on all skin-contact surfaces adds comfort for extended wear. Connecting via a 1.6-meter cable to compatible Sennheiser XS Wireless or Evolution Wireless bodypack transmitters, this headset mic integrates seamlessly into established Sennheiser wireless ecosystems without requiring adapters or workarounds.
