Our Verdict

Logitech G915 LIGHTSPEED

Logitech G815 LIGHTSYNC RGB

The Logitech G815 LIGHTSYNC RGB and the Logitech G915 LIGHTSPEED are near-identical keyboards, but the G815 is wired-only, while the G915 is wireless. They're available with the same switches and offer the same outstanding gaming performance. You can use the G915 with its USB dongle or over Bluetooth, and it has a multi-device pairing feature, which means you can use it with mobile devices, and you can pair to multiple devices simultaneously. On the other hand, the G815 has a USB passthrough, which the G915 lacks.
