The Roku 3's marquee feature is the remote's private listening mode: plug a pair of headphones into the remote's headphone jack and you can listen to whatever's playing on your Roku. Remote: Built-in headphone jack, plus Wi-Fi Direct But even that adapter is on the small side. My only complaint is the Roku 3 still requires a 'wall wart' AC adapter, unlike the Apple TV's sleeker integrated power supply. Noticeably missing is the standard-def AV output that was included on the Roku 2 XS, but that feature survives on the Roku LT, Roku 1, and Roku 2 if you need it. There's also a USB port on the side, which can be used for playing back digital media files, although not nearly on the same scale as competitors like the WD TV Play. The back panel is more compact than ever, with an Ethernet port, HDMI output, microSD slot, and power plug. Add in the Roku's neat remote with a built-in headphone jack - a killer feature for anyone with roommates or a late-night movie habit - and there are more than enough reasons buy the Roku 3 when you can already stream Netflix. And there's a lot to watch, with more than 1,000 channels including Netflix, Amazon Instant, HBO Go, Pandora, Hulu Plus, MLB.TV, PBS, and ( finally) YouTube. The Roku 3's updated processor and always-on design means you go from 'TV off' to 'House of Cards' much faster than alternative streamers, and the overhauled interface and improved cross-platform search lets you quickly find the content you want to watch. That's the question Roku has answered definitively with the Roku 3 ($99), by serving up more content sources than anyone else, with lightning-fast navigation and an onscreen interface that's finally competitive with the Apple TV. The Roku 3 is the best streaming-video box yet, with tons of content sources, lightning-fast performance, and an innovative remote with built-in headphone jack.
