The second generation of the M350 introduces a unique feature: a customizable middle button. This innovative addition allows users to personalize it for various functions, from sending emojis to swiftly accessing their favorite applications. The Keys 2 K380 keyboard comes equipped with similar shortcut functionalities. However, it’s worth mentioning that Logitech’s emphasis on a quieter typing experience might not cater to fans of the classic click-clack sound.
