The Roku Streaming Stick 4K was never meant to be seen again. The Roku Streaming Stick 4K, like its predecessor, is primarily a 3.7 x 0.8 x 0.5-inch dongle with an HDMI plug that plugs into the back of your TV. It does, however, include a 3.3 x 0.6 x 0.3-inch long-range Wi-Fi receiver in its USB power cable. A power adapter and the Roku Voice Remote with TV power and volume buttons are also included in the box. RokuOS 10.5 brings a slew of voice-centric updates, which those who purchase the Roku Streaming Stick 4K Plus with its always-listening Voice Remote Pro may appreciate more than those who purchase the Streaming Stick 4K with the regular Roku remote. Unlike the latter, which went straight to a suitable playlist, the Streaming Stick 4K let me choose which episode of Squid Games to watch, which made sense.
