Despite the shift toward wireless devices, many high-end and gaming keyboards remain wired or offer no Bluetooth option at all, largely because of measurable input delay. Bluetooth connections introduce a few extra milliseconds of lag between a keypress and its registration on a computer, which barely matters for typing but can affect gaming or music production. A 2.4GHz USB dongle connection offers a faster alternative to Bluetooth, often approaching wired performance for latency-sensitive tasks.

Testing from Polling Rate Test shows Microsoft's Xbox controllers report input at roughly the same 125Hz rate whether connected via USB cable or the proprietary Xbox Wireless Adapter, translating to about eight milliseconds of potential delay in either case. Bluetooth connections, by contrast, add an extra four to eight milliseconds of lag, varying with interference from nearby wireless devices.

A new comparison examines the practical differences between passive wired speaker setups and wireless Bluetooth systems, focusing on modularity, latency and cable management. It notes that wired systems let users swap components like amplifiers or speakers independently, while removing Bluetooth transmission delay from the audio chain. The piece also cautions that cables alone don't guarantee better sound quality if the source audio is already compressed.
