Amazon Echo Studio Review: A 3.5 kg Speaker That Doubles as a Zigbee and Matter Hub
Alexa's largest speaker, with a line-in jack, dual-band Wi-Fi, and built-in Zigbee, Thread and Matter bridging.
The Echo Studio is the heavyweight of Amazon's speaker line, literally: at 3.5 kg and 206 mm across it is built around audio hardware rather than being a puck with a speaker in it. For a smart home its value goes further, because it is one of the few speakers that is simultaneously a Zigbee coordinator, a Thread border router and a Matter bridge, so it can adopt Zigbee sensors and bulbs directly and connect Thread accessories without any separate hub. The catch is the ecosystem: Alexa only, with no Google Assistant, no Siri, no HomeKit and only partial Home Assistant support. Warranty is a short 90 days.

Who is the Echo Studio for?
Two audiences overlap here. The first wants an Alexa speaker that sounds like a speaker, and the size and weight are the giveaway that this one is designed for sound rather than convenience. The second wants fewer boxes: because the Studio includes a Zigbee coordinator, Thread border routing and Matter bridging, it can be the hub for sensors, bulbs and locks that would otherwise need a dedicated bridge, which for an Alexa home removes an entire device from the shelf.
What it offers
Dual-band Wi-Fi on 2.4 and 5 GHz plus Bluetooth, and a 3.5 mm line-in so it can take audio from a turntable, a TV or anything else without a wireless stack. Physical controls cover volume and play/pause, and there is a hardware microphone off switch, which matters for an always-listening device in a living room. Voice match recognises different household members for personalised responses. On the smart home side the Zigbee coordinator, Thread border router and Matter bridge combination is the standout, and it is available in charcoal or glacier white.
What to know before you buy
Alexa is the only assistant and the only platform: no Google Home, no Apple HomeKit, no SmartThings, and Home Assistant support is partial. The voice stack is entirely cloud based, with no local speech to text, conversation agent or text to speech, so it depends on an internet connection and on Amazon's servers for every request. Two safety listening features, glass break detection and smoke or CO alarm listening, require a subscription. There is no Ethernet port, no wall mount option, no temperature or motion sensing, and no screen or camera. Warranty is only 90 days, which is unusually short.
Is the Echo Studio worth it?
It is priced as a premium speaker, and for an Alexa household the hub functions effectively discount it, since they replace a separate Zigbee bridge. The line-in jack is a practical extra that most smart speakers omit. Weigh two things before buying: the complete dependence on Amazon's cloud for voice, and the 90 day warranty on a heavy piece of audio hardware. If your home runs on Google or Apple, none of this applies.
Frequently asked questions
Can the Echo Studio replace a Zigbee hub?
Yes. It includes a Zigbee coordinator, so it can adopt Zigbee devices directly, and it also works as a Thread border router and a Matter bridge.
Does it work with Google Home or Apple HomeKit?
No. Alexa is the only assistant and platform, with partial Home Assistant support.
Does it process voice locally?
No. Speech to text, the conversation agent and text to speech all run in the cloud, so it needs an internet connection to respond.
Can I connect a turntable or TV to it?
Yes, through the 3.5 mm line-in jack, which is unusual among smart speakers.
Is there a microphone mute?
Yes, a hardware microphone off switch, alongside physical volume and play/pause controls.
