About the Sennheiser EW 300 G4-865-S
The EW 300 G4-865-S pairs a condenser capsule handheld transmitter with the G4 receiver platform, delivering the brighter and more detailed sound of a condenser microphone in a wireless package. Condenser capsules excel at capturing vocal clarity and presence, making this system well-suited for vocalists who want a more studio-like sound on stage. The G4 platform provides reliable UHFThe TV-band radio range (roughly 470–608 MHz in the US) where serious wireless mics and IEMs live — better behaved than crowded 2.4 GHz. performance with straightforward setup.
The EW 300 G4-865-S is Sennheiser's mid-tier answer to the vocalist who wants condenser clarity without a cable tethering them to the stage. The 865-S transmitter carries a supercardioid condenser capsule — not the more common dynamic you'll find in the entry-level G4 systems — so the receiver is only half the story here. In the rack it occupies half a 1UThe standard slice of rack height: 1U = 1.75″.

That condenser capsule has real consequences at show time. You'll get more high-frequency detail and air than a dynamic-based wireless system, which is a genuine asset for singers with developed technique — but it also means the capsule is less forgiving of sloppy mic handling, proximity abuse, or loud stage washes bleeding into an open mic.

The G4 platform's front-panel display and locking menu are road-proven and fast to navigate at a dark stage-left position.

If your vocalist is a heavy-handed handler, plays loud stages, or the budget needs to stretch across four channels, the dynamic-capsule G4 systems or a competing mid-range option may serve better — the condenser's sensitivity is a feature until the stage environment makes it a liability. For a lead vocalist in a controlled environment, though, the 865-S capsule delivers a noticeably more open sound than what most wireless rigs carry.
In the rack
- Because it's half-rackThe standard slice of rack height: 1U = 1.75″. A 3U box takes three slices; half-rack gear pairs two units side by side in one., plan your rack panel before load-in — a Sennheiser GA 3 rack tray or a matched half-rack partner avoids a loose, rattling slot that will annoy you by the third show.

- If you're running multiple G4 systems, use Sennheiser's Wireless Systems Manager software to pre-coordinate frequencies before the show and push them to the receivers rather than hunting on the front panel during a busy load-in.
