Imagine a compact black box that slips behind your TV and suddenly unlocks 4K Dolby Vision, Dolby Atmos, HDR10+, and full Google TV functionality — all for under $70. That’s the Xiaomi TV Box S (2nd Gen). Released in mid‑2025 as a successor to the original Mi Box S, this device merges smart‑home voice control, wide streaming support, and value in one neat package.

This Lite media player may lack bells and whistles of premium devices, but it nails the essentials. For viewers wanting cinematic visuals without diving into niche hardware, it delivers surprising bang for the buck—especially in smart‑home setups wanting voice‑driven entertainment.

Features That Redefine Budget Streaming

Beneath its familiar squircle design, Xiaomi upgraded the internals significantly: a quad‑core Cortex‑A55 CPU paired with Mali‑G31 MP2 GPU, part of the Amlogic S905X4 family. Xiaomi claims up to 80 % faster CPU and 150 % faster graphics than the first‑gen model X (formerly Twitter)+12Dignited+12Dcolor+12Dcolor+12TechRadar+12Amazon+12.

Paired with 2 GB RAM and 8 GB eMMC storage, the unit handles mainstream 4K streaming easily. The box supports Dolby Vision, HDR10+, Dolby Atmos, and DTS‑HD audio, plus Miracast and Chromecast built in, giving flexibility most sticks don’t Dignited+1Wikipedia+1.

The shift from Android TV to Google TV on Android 11 boosts UI recommendations and cross-service search. Connectivity includes dual‑band Wi‑Fi—some units with Wi‑Fi 6—and Bluetooth 5.2, though not all SKUs support Wi‑Fi 6 TechRadar+1TechRadar+1.

Xiaomi’s redesigned remote now adds an IR blaster and a dedicated live‑TV button for Xiaomi TV+, replacing the old apps key, plus buttons for Netflix, Prime, and YouTube Xiaomi+3Dignited+3TechRadar+3.

How It Stacks Up Against Chromecast 4K and Roku Ultra

Let’s break this down:

Chromecast with Google TV 4K typically sells for ~$49–56. It has a slower GPU (~650 MHz vs. ~850 MHz in Xiaomi), and lacks Miracast support. Chromecast sometimes misses HDR support depending on the region Dignited+1Reddit+1. Xiaomi’s version handles both Dolby Vision and HDR10+ and adds Miracast for screen mirroring.

Roku Ultra is pricier (~$99–109). It does well with ports and remote features, but doesn’t support Dolby Vision or Miracast out of the box. Roku lacks the Google TV recommendation engine and voice‑assistant synergy Xiaomi offers at half the price TechRadar+3Dignited+3Xiaomi+3.

So: while Roku focuses on simplicity, Xiaomi doubles down on audio‑visual formats and smart‑home integration for budget users.

Price & Accessibility in Context

Xiaomi’s official pricing sits near $62 on Amazon US, though discounted as low as $49 on AliExpress, especially in Europe and Asia TechRadar. This undercuts the listing price of Chromecast, while delivering superior HDR and audio tech.

Google certification is a major plus. Users get access to verified apps, firmware updates, and regular support—unlike many cheap clones without official licensing DignitedXiaomi.

Upside Performance Meets Real-World Use

Users praise the polished UI and responsiveness. Amazon reviews mention fast app launches and image quality that feels sharper than expected at this price point. One review noted the voice‑control remote can even adjust TV volume via HDMI‑CEC Reddit+2Amazon+2Stuff South Africa+2.

Reddit threads reveal a nuanced story: while some say “Does not recognize my exFAT/NTFS USB drive,” others counter that exFAT support works, apps can be sideloaded, and device performance remains snappy post‑update Reddit. Another user confirmed fluent playback from USB drives and sideloaded apps.

Idle power draws hover around 3–4 W, with peaks under 7 W making it highly efficient for extended use.

However, some setup issues arise: certain users report audio glitches in HDMI passthrough unless they manually set PCM, and the lack of a hardware reset button forces manual resets via the UI. Also, automatic framerate switching is absent, which may affect playback of cinematic content on some TVs.

Smart-Home Integration in Actual Households

In smart-home environments, this device shines. Built-in Google Assistant controls streaming and other home devices: “Hey Google, play Stranger Things on Netflix” loads in seconds with 4K visuals and immersive audio. Smart routines can include streaming triggers or voice macros.

Users also deploy Plex and Kodi servers over Wi‑Fi, leveraging Xiaomi’s ability to decode VP9 and AV1 in cloud apps. Media files with bitrates up to 100 Mbps play smoothly from USB or network shares XiaomiDignited.

For those upgrading older TVs or smart setups on a budget, this meets user needs for voice, visuals, and ease-of-use.

Drawbacks Worth Considering

– Not all models include Wi‑Fi 6—half remain on Wi‑Fi 5, limiting futureproofing.

No built-in Ethernet: wired users must use USB-to‑Ethernet adapters.

Only 2 GB RAM restricts heavy multitaskers or gamers.

– No automatic framerate matching, which some viewing experiences demand.

– Several users report audio inconsistencies unless sound settings are tweaked manually.

Market Trends & Future Prospects

TechRadar’s 2025 roundup lists Xiaomi TV Box S (2nd Gen) as the “budget pick”—praising its sleek design and feature set, but noting the missing Ethernet port and AV1 codec absence compared to next-gen boxes TechRadarElHuffPost+14TechRadar+14Dignited+14.

With global smart-home adoption rising—Statista notes over 72 % of U.S. households now use streaming hubs with voice assistants—the Xiaomi Box fits perfectly into entry-level automated setups without forcing unnecessary complexity.

If Xiaomi continues firmware support and brings future codecs or optional memory upgrades, it could remain viable for years.

Final Reflections on Value and Experience

At around $60, the Xiaomi TV Box S 2nd Gen delivers Dolby Vision, Atmos, Google TV, smart-home voice control, and casting flexibility—features rare at this price level.

Yes, it has its quirks: limited RAM, lack of Ethernet, audio settings to tweak. But for homes wanting reliable streaming and Google Assistant integration on a budget, this is a standout choice in 2025.

For those wanting speed and voice control in one box, it’s hard to beat in 2025. Not flawless, but for anyone leaning into smart living, it’s a strong pick this year.
