Weeks after Amazon introduced an updated Fire TV lineup that included, for the first time, its own TVs, Roku today is announcing its own competitive products in a race to capture consumers’ attention before the holiday shopping season. Its updates include a new Roku Streaming Stick 4K and Roku Streaming Stick 4K+ — the latter which ships with Roku’s newer hands-free voice remote. The company is also refreshing the Roku Ultra LT, a Walmart-exclusive version of its high-end player. And it announced the latest software update, Roku OS 10.5, which adds updated voice features, a new Live TV channel for home screens, and other minor changes.
