Overview

The Sennheiser XSW 1-835 Dual-Vocal Set (508270) is a two-channel wireless microphone system built for live vocals, presentations, and events that require two simultaneous wireless mics. The package includes two SKM 835-XSW handheld transmitters, each equipped with Sennheiser's dynamic cardioid capsule — the same e835 element known for clear, detailed vocal reproduction with strong off-axis rejection. The single EM-XSW 1 DUAL receiver handles both channels, connecting to your mixer or PA via XLR outputs.

Setup is designed to be straightforward, even for non-technical users. The receiver's one-button scan finds clear frequencies in your environment, and each handheld syncs to its assigned channel with a single press. Icon-based indicators on both the transmitters and receiver display battery status, signal strength, and mute state at a glance. The receiver uses internal diversity antennas, eliminating protruding antenna hardware for a cleaner look on podiums or equipment racks. With support for up to 10 simultaneous XSW systems, the platform scales for multi-mic events. As an Amazon Renewed product, this set has been professionally inspected and tested to meet like-new functional standards, backed by the Amazon Renewed Guarantee for replacement or refund.

  • One-button frequency scanning and sync eliminates manual programming and gets both mics operational quickly.
  • Supports up to 10 simultaneous systems for multi-channel events and venues.
  • Internal diversity antennas on the receiver provide reliable signal reception with a clean, streamlined appearance.
  • Cardioid dynamic capsules deliver focused vocal pickup with good off-axis rejection for live use.

👎 Cons

  • As a Renewed product, it may show minor cosmetic wear and does not carry a standard Sennheiser manufacturer warranty.
  • Requires AA batteries for each handheld transmitter, adding ongoing battery costs for frequent use.
  • The XSW 1 series is an entry-level line that lacks advanced features found in Sennheiser's higher-tier wireless systems such as wider tuning bandwidth.

  • The receiver connects via XLR only, requiring adapters for systems that use other input types.

Frequently Asked Questions

This set includes two SKM 835-XSW handheld wireless microphones and one EM-XSW 1 DUAL receiver, giving you a complete two-mic wireless system in a single package.
Setup uses Sennheiser's one-button scanning and synchronization. The receiver scans for an open frequency, and with a single button press on each microphone, they sync to the receiver automatically — no manual frequency programming required.
Yes. The XSW 1 system supports up to 10 simultaneous systems operating in the same space, which makes it suitable for events, houses of worship, or venues running multiple wireless channels.
The SKM 835-XSW microphones use a cardioid (unidirectional) polar pattern, which focuses pickup on the sound source directly in front of the mic while rejecting noise from the sides and rear.
