Our Verdict

Logitech K380

Logitech K400 Plus

The Logitech K380 is a better keyboard than the Logitech K400 Plus. The K380's compact size is easier to travel with, and it can connect to any mobile device with Bluetooth support, unlike the K400 Plus. However, the K400 Plus does have a trackpad which makes it more ideal for a smart TV set up.
