Sennheiser XSW 1-825 Drahtloser Satz B: 614-638 MHz

Sennheiser XSW 1-825-B — Reliable UHF Wireless Vocal Set

The Sennheiser XSW 1-825-B is a plug-and-play wireless microphone system for singers, speakers, and presenters who need dependable stage performance without complicated menus. At its core sits the evolution e825 dynamic cardioid capsule, a Sennheiser workhorse trusted in live sound. The set pairs that microphone with a true-diversity UHF receiver, automatic frequency management, and one-touch remote sync, so the system is ready within seconds of being unboxed. This model is the right choice for performers stepping up from wired microphones who want freedom of movement on stage.

What Sets This Wireless Set Apart

What makes this system stand out in the entry-level wireless category is Sennheiser's use of a real evolution-series capsule rather than a generic OEM element. Antenna-switching diversity reception through integrated antennas eliminates dropouts without exposing fragile external rods. The 2.4 GHz low-power OQPSK sync link is active only during pairing, so it never interferes with the audio UHF transmission.
