Product Overview +

The Digital Standard for Modern Presentations

The Sennheiser SL Handheld DW is part of the SpeechLine Digital Wireless series—the world's first wireless system dedicated exclusively to speech. Whether you are leading a university lecture or a high-stakes corporate meeting, this handheld transmitter delivers a level of clarity and reliability that allows you to focus entirely on your message. The sleek, modern design is matched by an intuitive interface that makes professional wireless audio accessible to any user.

Effortless Technology, Sophisticated Sound

At the heart of the SL Handheld DW is the MME 865 supercardioid capsule. This high-end condenser element is designed to capture every detail of the speaker's voice while aggressively rejecting background noise and preventing feedback, even in rooms with active sound reinforcement. The system’s advanced digital architecture manages frequency selection and interference in the background, ensuring a rock-solid connection without any manual intervention.

Built for the Professional Workflow

Efficiency is built into every aspect of the SL Handheld DW. The transmitter features a prominent, ergonomically placed mute slider that allows presenters to control their own audio with ease. With an impressive 15-hour battery life, users can go through a full day of events without the anxiety of a dying battery. The persistent LC display ensures that tech crews and presenters alike can monitor the link status and battery health at a glance.

Centralized Network Control

For large-scale installations in Pakistan, the UAE, or Africa, the SL Handheld DW offers unparalleled management capabilities. Using the Sennheiser Control Cockpit software, IT and AV managers can monitor and control an entire fleet of microphones from a single dashboard. This network-driven approach simplifies maintenance and setup, ensuring that your audio system is always ready for the next speaker.
