Compare Redragon PENUMBRA K687 vs PENUMBRA K687 Pro Differences Side by Side

This comparison is for buyers deciding between Redragon's two closely related 75% aluminum keyboards. The choice is challenging because both share a CNC aluminum case, gasket mount, 5-layer sound dampening, hot-swappable sockets, and a control knob. The primary differentiator is connectivity, with the K687 Pro adding tri-mode wireless for a higher price, while the standard K687 is wired-only. This analysis breaks down where that extra investment matters most.
