Sennheiser EW 300 G4-HEADMIC1-RC Wireless Headset Microphone System

Reliable Wireless Audio for Business and Educational Presentations

The Sennheiser EW 300 G4-HEADMIC1-RC wireless headset microphone system is built for professionals who need crystal-clear audio and dependable wireless performance. Whether you're presenting in a conference room, teaching in a classroom, or leading a corporate seminar, this system gives you the tools you need for hands-free, high-quality audio.

With features like variable RF power, true-diversity reception, Ethernet connectivity, and a user-friendly OLED interface, this is a versatile wireless system that works seamlessly in multichannel setups across schools, universities, and corporate environments.

Professional Audio Quality with Wide Tuning and Interference-Free Operation

The system operates across a 50 MHz UHF tuning range and offers up to 2000 selectable frequencies, giving you reliable, interference-free audio even in crowded RF spaces. The auto-scan function finds the cleanest available channel so you can focus on your presentation without technical distractions.

The receiver features true-diversity reception, which constantly compares two signal paths and selects the strongest one. This technology ensures a consistent audio signal, even when moving around large spaces.

SL Headmic 1 Headset Mic with Lightweight, Comfortable Design

Included in this system is the Sennheiser SL Headmic 1 headset microphone, known for its omnidirectional pickup pattern and excellent speech intelligibility. It's extremely lightweight, discreet, and easy to wear for long periods, making it ideal for corporate trainers, keynote speakers, and lecturers.

The mic connects to the compact SK 300 G4-RC bodypack transmitter using a locking 3.5mm plug. This transmitter offers remote-control capability, programmable mute options, and adjustable input sensitivity, so it’s just as effective for quiet speakers as it is for more dynamic voices.

Rugged Bodypack Transmitter with Remote Control Capability

The SK 300 G4-RC transmitter is built with a robust metal housing and features a backlit LCD for quick settings adjustments. It syncs with the receiver in seconds via infrared pairing and operates for up to 8 hours using two AA batteries.

You can also use a rechargeable BA 2015 battery pack (sold separately) and charge it without removing it from the unit when paired with the L 2015 charger. For added functionality, the transmitter supports the RMS 1 remote mute switch (sold separately), which allows for push-to-talk or mute functions during presentations.

EM 300-500 G4 Receiver with Easy Menu Navigation and Custom EQ

The EM 300-500 G4 rackmount receiver offers a clean, high-contrast OLED display and a convenient jog wheel for fast menu navigation. It’s easy to operate even in low-light environments, making it a perfect choice for both portable setups and permanent AV installs.

This receiver includes 20 frequency banks with up to 32 compatible presets each, plus 6 custom user banks. You can also adjust the output signal with the built-in equalizer, boosting treble or reducing bass to fine-tune your sound. The adjustable 48 dB output range ensures a proper match with your PA system or mixing console.

Network Integration with Sennheiser Control Software

For advanced control, the receiver includes an Ethernet port that connects to both Sennheiser Wireless Systems Manager (WSM) and Control Cockpit software. These free tools give you centralized control over multichannel setups, real-time monitoring, and frequency coordination from your PC, smartphone, or tablet.

Whether you're managing multiple rooms or dozens of microphones, these software options make setup and daily use much faster and more reliable.

Expandable for Larger Wireless Audio Systems

The detachable BNC antennas allow for integration into larger multichannel systems. With the optional ASA 214 antenna splitter and remote directional antennas, you can extend your range and reduce interference in complex wireless environments.

This is especially useful for corporate campuses, event spaces, or schools that need to run multiple wireless channels at once without dropouts or interference.

Compatible with Evolution Series Components

One of the best features of the EW 300 G4-HEADMIC1-RC is its backward compatibility. You can mix and match it with transmitters and receivers from previous Sennheiser Evolution Wireless G1, G2, G3, and G4 systems. It's also fully compatible with EW 100 and EW 500 series components, giving you full flexibility as your system grows.

Adaptable with a Wide Range of Microphone Options

Sennheiser offers multiple microphone options to expand or customize your wireless setup. For example, the ME 2-II lavalier microphone is great for on-camera work or spoken word presentations, while the SKM 300 G4 handheld transmitter allows for quick handheld use with a range of interchangeable mic capsules to suit different vocal styles.
