Features:
Get a clean, modern desk setup and make a visual statement thanks to the ultra-slim profile and minimalist design of the keyboard.
K580 can be swiftly paired via BT wireless technology or Unifying USB receiver, providing 10m stable and reliable wireless connection.
The compact design helps you get the most out of your workspace. With a number pad and all the keys you need, there's less arm extension, so you can work comfortably for longer time.
The keyboard works with your smartphone and tablet, easy to switch typing between two devices with the same keyboard. Start typing a report on your computer, then switch to type a message on your phone-which can be placed in the built-in phone bracket for better multitasking.
Low-profile key switches provide smooth laptop-style typing and ultra-quiet work experience for you and those around you.
