About the Roku Ultra 4670R (2019 model)

Access to the most shows and movies — in full 4K

What an exciting time for binge-watchers! There are more new shows, movies, and streaming video services out there than ever before. And the Roku Ultra connects to your TV and serves up the largest selection of video content I've seen. That includes the most 4K and HDR choices available in one streaming box.
Roku Ultra with included remote and earbuds

The compact Roku Ultra fits into your TV setup and serves up a ton of streaming 4K and HD channels.

Access to the most shows and movies — in full 4K

What an exciting time for binge-watchers! There are more new shows, movies, and streaming video services out there than ever before. And the Roku Ultra connects to your TV and serves up the largest selection of video content I've seen. That includes the most 4K and HDR choices available in one streaming box.

Just be warned — ever since I connected a Roku to my LG OLED TV, I've become spoiled. Now I only want to watch visually-striking shows like Stranger Things and Narcos in full 4K. And Roku's latest version of the Roku Ultra offers their fastest processing yet. That means even smoother performance than previous generation Roku players. 

Do "smart TV" owners need a Roku?

While most 4K TVs have some streaming services baked in, Roku offers the most complete list of 4K options I've seen. Netflix, Hulu, Amazon Instant Video, and Vudu are all available in 4K. New video services Disney+ and AppleTV+ are also available with 4K and HDR content.   

Plus there's a ridiculous amount of standard HD streaming channels – movie channels, news, kids, sports, you name it. I use my Roku to watch baseball games on MLB.TV and order UFC pay-per-views on ESPN+. I can't watch either on my Smart TV without the Roku. 

"Point anywhere” remote 

Roku's redesigned remote is easy to use and can even control your TV's volume. Since the remote communicates over Wi-Fi, you can store the player out of sight and still have full control.

Roku Ultra 2019 remote

Customize the remote's "1" and "2" button to instantly pull up a favorite channel or playlist.

Worried about keeping track of another clicker? You can press the "find my remote" button on the Roku Ultra, and the remote will make a sound.

JBL headphones for personal TV watching

Roku also includes a nice pair of JBL earbuds. They connect to the remote, so you can watch TV without disturbing others. JBL has done a lot of great research to hone the sound of their company's in-ear headphones. So you can expect the audio experience to be on-par with the action on the screen

Unbiased search — with your voice

The remote also features voice control. Tap the voice search button on the remote, and call out the name of a movie, show, or actor. Roku's “unbiased search” will hunt through the top channels for the cheapest way to watch. That's pretty handy for cost-conscious cord-cutters who no longer pay for cable.

A new design touch for this player's remote — there are two "personal shortcut" buttons you can program by voice. When you press one of them, you instantly call up whatever channel, playlist, or search that you've saved. 

My Roku experience: It's not just for cord cutters

While I've dabbled in cord-cutting, I'm currently a cable subscriber. Still, I call the Roku I bought for my bedroom TV the best bang-for-my-buck purchase I've made all year. It gives me on-demand shows from my cable channels like FX, HBO, AMC, and more. So I can watch Succession or Better Call Saul on my own time — without having to rent another cable box.

Remote app with personal listening mode

Roku's free mobile app lets you operate the player using your Apple® or Android™ device. Choose what you want to watch and control video playback from your phone. You can also connect headphones and hear TV sound.

ROKU is very easy to use for new folks or less technically oriented people,, interface is very user friendly. Product wise, this unit is one of very few with LAN cat5/6 hard wire PORT for direct wiring vs using WiFi (which is not perfect as yet),, if don't like wiring consider Powerline Adapters like Netgear (have used for over 10-years) and as General Contractor who's fixed bld, surprised it works but it DOES (even hd with VUDU) [ David  Dec 02, 2019 ]
