Roku Ultra

Roku Ultra

The Roku Ultra is the company's most powerful player. It supports HD, 4K, HDR, and Dolby Vision for prime visual experiences. It connects via 802.11ac dual-band MIMO Wi-Fi or ethernet and launches relatively quickly. Dolby Atmos sound helps immerse viewers, while the voice remote (with shortcut buttons) allows TV control with simple vocals. The box also comes with wired headphones, a pair of AA batteries, a power adaptor, and an HDMI cable. Users with the Roku mobile app can also control the player via their phone, like an alternate remote. Finally, there's local playback with the USB 3.0 port. The Roku Ultra (model 4800R) measures 4.9" x 1.0" x 5.0" and weighs 5.9 ounces.
