Xiaomi TV Box S 3rd Gen review

A Google TV 4K box with Dolby Vision, HDR10+, DTS:X and 32 GB, with everything in the box.

In brief

Dolby Vision and HDR10+ both, at $105 on October 25, 2026 — and the only box here under two hundred dollars that publishes its HDR formats, its DTS:X support and everything in the box. Key figures: 4K Ultra HD Google TV streaming box supporting 3840 by 2160 at 60 frames with Dolby Vision and HDR10+, Dolby Audio and DTS:X, a quad core processor to 2.5 GHz with ARM G310 V2 graphics, 2 GB of memory and 32 GB of storage, dual band Wi-Fi, Bluetooth 5.2, HDMI 2.1 and USB 2.0, with Google Cast, supplied with a voice remote, power adapter, HDMI cable and manual. Amazon.com had an offer at $105 on October 25, 2026.

What the maker puts in writing

  • “Supports 4K resolution (3840 x 2160) at 60FPS, Dolby Vision, and HDR10+ for enhanced contrast, brightness, and color accuracy. Delivers immersive audio via Dolby Audio and DTS:X surround sound”
  • “Equipped with a Quad-Core CPU (up to 2.5GHz) and ARM G310 V2 GPU… Includes 2GB RAM and 32GB internal storage (ROM)”
  • “Runs the latest Google TV OS, offering personalized content recommendations, access to thousands of streaming apps (Netflix, YouTube, Disney+, etc.), and voice control via Google Assistant”
  • “Features dual-band Wi-Fi (2.4GHz/5GHz), Bluetooth 5.2, HDMI 2.1, and USB 2.0 ports… Supports decoding of 4K 60FPS video formats and Google Cast for screen mirroring”
  • “Comes with Xiaomi TV Box S (3rd Gen), voice remote control, power adapter, HDMI cable, and user manual. Compact design (95.25 x 95.25 x 16.7 mm (3.75 × 3.75 × 0.66 in))”

Both HDR formats, which only the Apple also manages

Supports… Dolby Vision, and HDR10+.

The two are incompatible, and that is why having both matters.

Unlike basic HDR10 — which carries one set of brightness instructions for a whole film — both of these carry instructions scene by scene, so each shot is mapped to what your display can actually show. They achieve it by different and mutually exclusive methods: Dolby Vision is licensed and proprietary, HDR10+ is royalty-free. Manufacturers pick sides.

So a box supporting only one falls back to plain HDR10 on a television that supports the other.

On this shelf: this at $94.99 and the Apple TV at $234.99 publish both. The Formuler at $121.43 publishes “HDR 10” alone. The Infomir and both Ugoos models publish “HDR” without naming a format. The HK1 and both ONN boxes publish nothing.

And DTS:X, which nothing else here names

Delivers immersive audio via Dolby Audio and DTS:X surround sound.

DTS:X is the competitor to Dolby Atmos — object-based surround, where sounds are placed in three-dimensional space rather than assigned to fixed channels — and a good many discs and some streaming services use it.

The audio formats across this shelf: Dolby Audio and DTS:X here · Dolby Atmos (Apple) · eight-channel Dolby Digital Plus (Infomir) · nothing stated on the other six.

What a box needs to do is pass the bitstream through to an amplifier that decodes it. Naming the format is how you know it will.

The box contents are published in full

Xiaomi TV Box S (3rd Gen), voice remote control, power adapter, HDMI cable, and user manual.

Four of the nine listings here publish contents: this, ONN’s Android TV (HDMI cable), Ugoos SK1 Lite (remote, adapter, cable, manual) and Ugoos AM6B Plus (remote, two external antennas, adapter with a choice of plug, cable, manual).

The other five — including the $234.99 Apple and the $62 ONN — publish nothing.

And the voice remote is the part worth having: it puts Google Assistant on a button, so finding a program is spoken rather than typed on an on-screen keyboard.

Ninety-five millimeters square and ninety-one grams

95.25 × 95.25 × 16.7 mm, published in the listing, and 91 g in the catalog — the lightest and among the smallest on this shelf.

Which matters practically: a box this size tucks behind a television or onto a shelf without a plan, where the ONN boxes at 6.89 × 3.78 × 2.05 in (175 × 96 × 52 mm) and the Apple at 4.02 × 5.98 × 2.01 in (102 × 152 × 51 mm) need a place.

The Formuler Z10 is comparable at 3.70 × 3.70 × 0.65 in (94 × 94 × 16.5 mm), and the Infomir at 4.72 × 3.07 × 0.83 in (120 × 78 × 21 mm).

Google TV, and what it sells

The latest Google TV OS, offering personalized content recommendations.

Google TV is the interface layer that replaced Android TV’s home screen — same underlying Android, same Play Store, a different front page that aggregates recommendations across your services and keeps one watchlist.

ONN’s box at $62 also runs it; ONN’s box at $58.87 runs the older Android TV, which shows rows of apps and leaves you to open one.

Which you prefer is taste. Google TV helps if you subscribe to several services and want one place to look.

HDMI 2.1 is published too, which three boxes here manage — this, the Infomir and the Ugoos SK1 Lite.

What is not published

No Ethernet port. For internet streaming that is usually fine: a 4K stream is 15 to 25 Mbit/s, which 5 GHz Wi-Fi handles unless the router is far or the house is busy. Where a wired port earns its place is local playback — a high-bitrate 4K file from a network drive can exceed 100 Mbit/s. Five boxes here publish a port: 1000M on the HK1 and both Ugoos, 100M on the Infomir and Formuler.

No AV1 codec. The bullet says “supports decoding of 4K 60FPS video formats” without naming them — and AV1 is the one that matters now, since YouTube and Netflix both use it. Only the Infomir at $99 and the Ugoos SK1 Lite publish it.

No chipset model. “Quad-Core CPU (up to 2.5GHz)” gives the core count and the clock but not the part — where the Infomir names an Amlogic S905Y4-B, the HK1 an S905X4, the Ugoos models an S922X-J and an S928X-K, and Apple an A15 Bionic. The chipset is what decides which codecs decode in hardware.

Two gigabytes of RAM, against four on the HK1 at $78.62 and both Ugoos models. For one app at a time it is sufficient; switching between apps will reload them.

What gets asked most

Why does having both Dolby Vision and HDR10+ matter?

Because the two are incompatible, and a television supports one, the other, or both. The bullet publishes support for "Dolby Vision, and HDR10+ for enhanced contrast, brightness, and color accuracy." Both are dynamic metadata formats: unlike basic HDR10, which carries one set of brightness instructions for a whole film, they carry instructions scene by scene, so each shot is mapped to what your display can actually show. They achieve that by different and mutually exclusive methods — Dolby Vision is licensed and proprietary, HDR10+ is royalty-free — and manufacturers pick sides. So a box supporting only one will fall back to plain HDR10 on a television that supports the other. On this shelf, only this and the $234.99 Apple TV publish both. The Formuler at $121.43 publishes "HDR 10" alone; four listings publish no HDR format at all.

Is two gigabytes of RAM enough?

For streaming, yes — and it is the figure where this box sits below its neighbors. The bullet publishes "2GB RAM and 32GB internal storage". RAM is what decides whether switching between apps reloads them from scratch or resumes them instantly: with 2 GB, a television platform typically holds the system plus one or two apps in memory. In practice a streaming box is used one app at a time, so the effect is a brief reload rather than a failure. The shelf, for comparison: 1 GB (Infomir, $99), 2 GB (this and the Formuler, $121.43), 4 GB (HK1 at $78.62, and both Ugoos models). So the HK1 at $78.62 publishes twice the RAM for sixteen dollars less — though with DDR3 memory where the dearer boxes use LPDDR4. What this box has instead is 32 GB of storage, four times the 8 GB of the ONN and Formuler.

Does the missing Ethernet port matter?

It depends entirely on what you stream and from where. The bullet publishes "dual-band Wi-Fi (2.4GHz/5GHz), Bluetooth 5.2, HDMI 2.1, and USB 2.0 ports" — and names no Ethernet. For internet streaming that is usually fine: a 4K stream is 15 to 25 Mbit/s, which 5 GHz Wi-Fi handles comfortably unless the router is far away or the house is busy. Where a wired port earns its place is local playback — a high-bitrate 4K file from a network drive can exceed 100 Mbit/s, and Wi-Fi under load is where buffering starts. On this shelf five boxes publish a port: 1000M on the HK1 and both Ugoos models, 100M on the Infomir and Formuler. The $234.99 Apple TV here is also the Wi-Fi variant with no Ethernet, as its own title states.
