Sennheiser XSW IEM EK (A) In-Ear Monitoring Bodypack Receiver

Lightweight yet rugged, the XSW IEM EK (A) bodypack receiver from Sennheiser is the perfect basis for their XS Wireless IEM series. This stereo receiver bodypack is built with the live stage in mind. Fine-tune your settings to achieve the perfect focus on your individual mix, with functions such as balancing, EQ, channel selection, or manual frequency.

A status LED keeps you informed about battery and connection status, while an LCD offers settings readouts for more detailed data.

With XS Wireless IEM, you can easily link additional receivers to one transmitter – connecting more band members to a new level of detail. This scalability makes it easy to grow or adjust your sound setup as your musical group expands and changes over time.
