Upgrade Your Ergonomic Workflow
EM11 Pro builds on EM11 with four key upgrades: web-based customization, adjustable DPI (800–7200), a side scroll wheel, and multi-device connectivity. All in a refined ergonomic shape for smoother daily work.
Web-Based Button Customization
Customize shortcuts, macros, and button functions directly in your browser — no software to install.
Assign your most-used actions to any button, cut down repetitive clicks, and build a faster workflow for spreadsheets, design tools, or everyday browsing.
Adjust DPI for Every Task
Switch between 800 and 7200 DPI on the fly. Lower DPI gives you pixel-precise control for editing; higher DPI glides across large or multi-monitor setups with ease.
Comfortable Ergonomic Design
The 58° vertical angle keeps your wrist and forearm in a natural handshake position. Paired with a sculpted shape and supportive grip, it reduces wrist strain and keeps you comfortable all day.
