The Roku Ultra is a premium streaming box with 4K resolution, HDR10+, and Dolby Vision support, paired with Dolby Atmos audio for cinematic sound. It runs Roku OS, offering access to thousands of apps (Netflix, Prime Video, Disney+, Paramount+, etc.) with minimal ecosystem lock-in. The standout feature is the Roku Voice Remote Pro — rechargeable, backlit, hands-free voice control, and a lost-remote finder. Wi-Fi 6 and optional Ethernet ensure reliable streaming; Bluetooth headphone mode lets you listen privately. At $86.99 (13% off MSRP $99.99), it's positioned between mid-range sticks ($30–$50) and high-end boxes (Apple TV 4K $129+). Ideal for cord-cutters wanting fast performance (30% quicker than other Roku players), premium picture/sound, and Roku's ad-lite home screen. Compact (4.9" × 5" × 1"), it fits most entertainment centers. 2-year manufacturer warranty included.
