Overview

The Sennheiser XS Lav USB-C Mobile Kit bundles a professional-grade lavalier microphone with essential accessories for mobile content creation. The microphone itself features an omnidirectional capsule that delivers clear, natural speech reproduction with a signal-to-noise ratio of 78 dB and a noise floor of just 22 dB. Its USB-C digital connection bypasses the analog audio circuitry in smartphones and laptops, resulting in a cleaner signal path and more consistent recording quality compared to traditional 3.5mm lavalier microphones. The 2-meter cable gives you comfortable working distance between the clip-on mic and your recording device without excess cable to manage.

What sets this apart from standalone lavalier mics is the included Mobile Kit accessories. The Manfrotto PIXI Mini Tripod provides a stable, compact base for your phone, while the Sennheiser Smartphone Clamp securely holds your device in place for hands-free recording. The microphone also ships with a clip for attaching to clothing, a windscreen for outdoor use, and a storage pouch to keep everything organized. For content creators shooting talking-head videos, conducting interviews, or joining video calls while traveling, this kit provides everything needed for a clean, professional audio setup without piecing together components from different manufacturers.
