What will you mostly use it for?
The K707 HE is the gaming-focused pick here, with explicit 8K polling and a feature for assigning two actions to one key. The K687 HE takes the edge for office tasks, programming, and content creation if its knob and compact layout are a better fit. For travel, the K707 HE is lighter, though both require a wired connection. For modding-oriented buyers, the K687 HE offers the more substantial listed materials and more layers of sound dampening, but both are limited to magnetic switches.
