Sennheiser 508493 XSW-D Wireless Instrument Microphone Set

The Sennheiser XSW-D Instrument Base Set is a digital wireless system designed to replace the cable between your instrument and amplifier or pedalboard. The transmitter plugs directly into your instrument's 1/4" output jack, while the receiver plugs into your amp or effects chain input. There is no manual pairing process — power both units on and they connect automatically, with built-in channel allocation and interference management handling frequency selection behind the scenes. Operating on the license-free 2.4 GHz band, the system works anywhere in the world without permits.

Audio quality is a standout feature, with a 106 dB signal-to-noise ratio ensuring your tone comes through cleanly without added hiss or coloration. The miniature form factor keeps both the transmitter and receiver discreet, and the included beltpack clip gives you a mounting option if the direct-plug orientation does not suit your instrument. Each unit houses a rechargeable lithium-ion battery rated for 5 hours of continuous use, and USB charging during operation means you can top up between sets without going silent. For guitarists, bassists, and other instrumentalists who want wireless freedom without complex setup, the XSW-D delivers a professional-grade experience in a remarkably simple package.
