Sennheiser EW IEM G4 Wireless In-Ear Monitoring Set

If you already know you want a wireless earpiece system and you want more — more range, more frequencies, more control — the Sennheiser EW IEM G4 is the step up from the XS. Engineered for professional live sound, this is a rugged all-in-one UHF wireless monitoring system built for daily use on stage.

The system works with a standard 3.5mm earpiece or an induction neckloop — both of which we stock separately. It is also compatible with our IFB-EW-KIT presenter earpiece kit.

The half-rack stereo transmitter has a full-metal housing and an OLED display for full visibility of your setup. Up to 42 MHz switching bandwidth gives you 1,680 selectable frequencies across a stable UHF range, with 20 factory-preset frequency banks (up to 16 channels each) and 6 programmable banks — all intermodulation-free. RF output power is switchable between 10 mW, 30 mW, and 50 mW (subject to country regulations), and transmission range reaches up to 100 metres. The transmitter syncs to receivers via infrared and is compatible with Sennheiser WSM software for flexible frequency coordination across larger setups.

The bodypack receiver is robust and stage-proof, paired with IE 4 in-ear headphones delivering clarity across the full frequency spectrum. Signal-to-noise ratio exceeds 90 dB.

Included: IE 4 In-Ear Headphones

The set includes Sennheiser's IE 4 in-ear headphones — outstanding sound quality, wide dynamic range, and strong bass response. Exchangeable ear sleeves give a secure, comfortable fit with good ambient noise isolation.
