General

While setting yourself up with a live monitoring system can be complicated and expensive, Sennheiser serve up the affordable, fuss-free and complete solution in the form of the XS Wireless IEM wireless in-ear monitoring system. Compiling an XSW IEM EK stereo receiver beltpack, an XSW IEM SR stereo transmitter and IE4 in-ears as well as a matching antenna, rack mount kit, various power supplies to support international use and a pack of AA batteries, this Sennheiser-set comes with everything you need to monitor yourself or someone else in the band.

The XS Wireless IEM: Time to Level Up

Fully wireless and easy to use, the XSW IEM monitoring system allows you to roam around the stage while you keep tabs on the monitor-mix in the midst of screaming floor monitors and PA speakers. The system operates on the professional UHF frequency band based on pre-defined frequency ranges that are quick and easy to configure, while features such as an integrated EQ, a limiter and various monitoring modes flesh out a stage-focussed solution the world hasn't seen before.

Various Monitoring Modes and Maximum Range

The Sennheiser XSW IEM can be set up in one of three modes: Stereo, Mono and Focus. Stereo Mode gets you improved audio quality and an enhanced spatial representation of the sound; Mono Mode ensures a better range and a firmed-up sound; and Focus Mode combines two mono signals, allowing you to effortlessly toggle between both and pick what you want to hear. Furthermore, you're free to connect as many bodypacks to a single transmitter as needed so that every performer in a large group is able to receive the monitor mix and, with 30mW of transmitting power and a 100-metre maximum wireless range at your disposal, you're certainly all set to take even the biggest stage by storm.
