Amazon Echo Dot (4th-gen) full review

According to Amazon, the Echo Dot is its best-selling speaker (not just smart speaker - all speakers). And it isn’t hard to see why: it’s inexpensive and Alexa can do exactly the same things she can on Amazon’s more expensive speakers.

As with the third generation, you have a choice of two models, one without a clock display and one with.

Because the two devices are identical apart from the display – and price – we decided to cover them both in a single review.

Features & Design

Unlike in previous years, the Dot is identical in design to its larger counterpart, the Echo 4. It’s simply smaller – a 100mm diameter instead of 144mm.

Here's how the two sizes compare:

The Dot comes in the same three colours as the big Echo: Charcoal, Glacier White and Twilight Blue. Its plastic body is made from 50% recycled plastic, 100% recycled aluminium and 100% recycled fabric.

The usual four buttons are still on top for adjusting volume, muting the mic and stopping the alarm that goes off when a timer ends (among other things).

As with the bigger Echo, the light ring on the fourth-generation Dot is at the base and reflects off your table, or wherever you choose to place your Dot.

This can make it harder to see, especially when other items are on the table or shelf near the dot as they tend to obscure it from view.

There’s no threaded hole in the base of the Echo Dot and the 3.5mm minijack socket is an output only: it can’t be configured to be an input in the Alexa app like the bigger Echo.

If you pay a very reasonable £10/$10 extra for the clock model you get an LED display which curves around the front and shines through the fabric. There’s no difference between the 4th-gen and 3rd-gen models in terms of what it can show: the time, timers, outdoor temperature, alarm times and display the volume and screen brightness levels – from 0 to 10.

Echo Dot 4 review (with clock)

Internally, there’s the new AZ1 processor which allows Alexa to respond faster as it can process some of what you say on the device itself, but with less available memory than the Echo and Echo Show 10, the Dot and Dot with clock don’t get the full range of new features which, as far as we know, means they won’t be able to handle the new, more natural-sounding voice of Alexa.

It’s worth noting that the Dot doesn’t have the Zigbee hub of the Echo 4, nor does it get a temperature sensor. Alexa can report only the outside temperature, which she gets from weather services.

Sound quality

The new Dot and Dot with clock have a single 1.6in speaker which is the same size as the 3rd-gen Dot, but being inside a sphere means better bass.

And so the fourth-generation Echo Dot sounds exactly like the third, but lower frequencies are more noticeable. As with all Echo Dots, they’re not the best choice for listening to music if you care about sound quality, but they are great for listening to the radio, podcasts or simply Alexa’s voice.

If even the larger fourth-gen Echo, reviewed, isn’t going to satisfy you with its audio quality, then hooking up your own speaker(s) to a Dot could be a good way to save money if you can live without the Echo’s extra features such as that smart hub.

Remember, too, that the Echo Dot and clock version have built-in Bluetooth which works both ways. You can stream music from your phone or another Bluetooth device to it, but you can also pair a Bluetooth speaker to get better sound from the Dot, so long as the speaker doesn’t need a PIN to pair it.

Price & Availability

The fourth-generation Echo Dot is the same price that Dots have always been: £49.99/US$49.99/AU$79.99 and you can buy one from Amazon in the UK,  Amazon in the US and Amazon Australia

The Echo Dot with clock is £10/$10/$40 more expensive at £59.99/US$59.99/AU$99.99.

If you’re in the US, you also have the choice of a third model, the Kids Edition. Amazon has come up with more fun designs this year: you can pick between a tiger or panda.

Those are both $59.99 and have a child-friendly version of Alexa along with a free year of Amazon Kids+ (previously called FreeTime Unlimited). That includes age-appropriate Audible books, interactive games and educational skills.

For an extra $15, you can buy an Echo Dot Kids Edition plus an Echo Glow, which is a smart, multicolour nightlight.

Echo Dot 4 review (with clock)

If you’re happy to go without the new processor and new design, the third-generation Echo Dot is still sold alongside the new models for £39.99 in the UK, though it's discontinued in the US.

The latest Echo Dot may have a new design and faster, more power-efficient processor but to all intents and purposes isn’t really much different from the old one. It sounds largely the same and has the same capabilities. The same goes for the version with a clock.

That doesn’t mean you shouldn’t buy one of the new fourth-gen models, but there’s no reason to upgrade if you have a third-gen Echo Dot.
