It's round; It's also got good bass and improved overall audio quality; Adds built-in Zigbee smart home hub capability.

Privacy is still a concern; Not truly omnidirectional; Besides audio and design, most upgrades are very incremental.

With its new spherical design, the Amazon Echo Dot (4th Generation) is a far more interesting-looking product than the old model, better able to slip into your home without standing out for the wrong reasons. While there's nothing new about what Alexa can do on this model, Amazon has boosted the audio quality so the occasional bit of music is pretty good and voice replies are really easy to understand. If you've got the previous model there's little reason to upgrade, but for those looking for a new small smart speaker, this is the model to buy.

Looks fantastic; New controls are easier to reach; Forward-firing speaker is clearer;

Low power mode has big restrictions; Not ideal for lots of music;

Amazon's flagship speaker gets better and smarter ... all round.

New design; ZigBee / Sidewalk radios; Stereo sound; Simple setup; New tap to snooze feature

ZigBee pairing hit or miss; Waiting on new features; Bass not much better

Ask Alexa to do something and it is done. Marvellous. We love her.

the music has a wide and varied selection and is of good quality

Product was easy to setup. Was quite surprised at the bass levels on such a small speaker

very good as it is used nearly every day

The 4th-gen Amazon Echo is the most well-rounded smart speaker. The Amazon Echo is the most well-rounded smart speaker, and I’m not just talking about its looks. Yes, the spherical shape of the 4th-generation Amazon Echo makes it visually interesting, but the smart home networking tech and Amazon’s...

Sleek spherical design, Good audio for price, Great smart home skills, Audio in/out port

I wish it had a clock, Audio not as good as Sonos One
