Questions about this item

How quiet is the K865 keyboard during all-day typing sessions?

The K865 uses linear Red mechanical switches that produce a lower sound profile than tactile or clicky variants, keeping noise minimal for extended work periods.

What do I need to connect both the K865 keyboard and G304 mouse to my computer?

The K865 pairs via Bluetooth or its included Logi Bolt USB receiver, while the G304 uses its own LIGHTSPEED USB receiver; each device requires an available USB-A port for its dongle.

Will the K865 keyboard and G304 mouse work with my older Windows 10 PC and existing USB-A ports?

Yes, both devices support Windows 10 or later and connect through standard USB-A receivers, so they operate alongside your current hardware without adapters.
