Roku calls the services and apps available on its devices Channels and currently offers thousands of choices in the Roku Channel Store. All of the big streaming media names are available, including Amazon Prime Video, Hulu, Netflix, and Sling TV, along with many smaller, niche apps and services for movies, sports, weather, news, and international content. It also has Apple AirPlay support. The Roku Streaming Stick 4K, Streaming Stick 4K+, and Ultra all stand out as top choices. Each offers 4K video with HDR10 and Dolby Vision support. The Streaming Stick 4K+ and Ultra feature Roku's Voice Remote Pro, which boasts hands-free voice control, a remote finder function, and a headphone jack for private listening. The Ultra is the most expensive, but it's the only model with Ethernet (for wired network connections) and USB ports (for playing media directly from a USB drive). On top of dedicated media streamers, Roku also offers a soundbar with media streaming functions, the Roku Streambar Pro ($179.99). It's expensive as a media hub, but that price is more than reasonable for a modest stereo soundbar with the additional benefit of streaming 4K video. If you're looking for a smaller package that still has all of the features (but not the audio power) of the Streambar Pro, check out the Roku Streambar. You can pair either device with the Roku TV Wireless Speakers for surround sound and the Roku Wireless Subwoofer for more rumble. Roku has also established itself as one of the biggest companies for smart TV platforms with Roku TV. The company both makes its own TVs and offers its technology to manufacturers to incorporate into their screens. A dozen companies including Hisense use it on some of their TVs. Roku TVs work just like Roku media streamers, except that they are built directly into the sets.
