Amazon Echo (4th Gen) review: offers better audio performance

The next generation smart speaker with enhanced features.

At this point, there’s no need to explain what the Amazon Echo is. What started out as an invite-only experiment in late 2014 is now the most popular family of smart speakers on the market, with Amazon easily beating Google and Apple. The Amazon Echo (4th Gen) is the newest Echo option. It’s the middle child between the Echo Dot and the Echo Studio, and for just $100, it has a lot to offer. Amazon will release a 5th-Gen Echo Dot in 2022, but it doesn’t look like they have any plans for a 5th-Gen Echo right now. Even though it came out more than two years ago, it looks like the Echo (4th Gen) is still doing well.

Amazon Echo (4th Gen): Description

If you still don’t like how Alexa works compared to something like Google Assistant, there’s nothing about the Amazon Echo (4th Gen) that will change your mind. But right now, this is one of the best speakers you can buy if you already like Alexa or if you have been meaning to join the crowd. The big question about the Echo (4th Gen) is how it looks, so let’s start there. Before this one, every Echo speaker had a tall, cylindrical shape that changed just a little bit with each new model.

The 2nd Gen model was the first to have fabric, the 3rd Gen Echo made the shape a bit more rounded, and the current 4th Gen Echo has become completely round. The spherical shape of the 4th-generation Amazon Echo is a big change from the tall cylindrical shape of earlier models. Still, the Echo is one of the best smart speakers you can buy today because of what’s inside it. Amazon has made a noticeable improvement to the sound quality, which is just one of many things that make this one of the best smart home devices of its kind.

Amazon Echo (4th Gen): Design

Amazon Echo (4th Gen) review

The fourth-generation Echo is almost a sphere, with a height of 5.2 inches and a width of 5.7 inches. It comes in black, blue, or white. Amazon says that the aluminum and fabric used in its Echo speakers are both made from 100% recycled materials. It’s a fun new design that looks like the upcoming HomePod mini from Apple. The light ring has been moved from the top of the speaker to the bottom. This gives it a less direct glow, but you can still tell when you say your chosen wake word for Alexa because it lights up blue. The top panel has buttons for Alexa, turning up or down the volume, and muting the mic. On the back is where the power adapter plugs in and where the 3.5mm audio output is.

Under the fabric are a 3-inch woofer and two 0.8-inch front-firing tweeters, which allow the Echo to support Dolby audio (but not Dolby Atmos surround sound, like the Echo Studio, which has four drivers, including a 5.3-inch woofer). They have the same size drivers as the Echo Plus and the third-generation Echo, but they have two tweeters instead of one. Like the Echo Plus, the fourth-generation Echo has a smart home hub built in. It is a Zigbee hub, and it also works with Bluetooth Low Energy (BLE) and Amazon Sidewalk. This lets low-bandwidth devices have a longer range.

Amazon Echo (4th Gen): Features

Amazon Echo (4th Gen) review

The Echo has Amazon’s AZ1 Neural Edge processor, which is a brand-new silicon module made to speed up applications that use machine learning. With AZ1, powerful inference engines can run “on the edge,” or on the device, starting with an all-neural speech recognition model that should process requests faster and make Alexa even more responsive by “learning” and understanding more about you over time.

As long as that doesn’t completely freak you out (you can turn off the Echo’s microphones whenever you want), your choice between Google Assistant and Amazon Alexa will probably come down to how well they work with other devices in your home. We don’t see much of a difference, and the service here is much better thanks to a wide variety of third-party services, such as BBC, The Guardian, and Pointless smarts in the UK.

The Echo is easy to set up and use with your smartphone (Bluetooth must be turned on) and wi-fi. Once you have linked your streaming service accounts, it can play music from Amazon Music Unlimited, Apple Music, Spotify, or Deezer over Wi-Fi. Even if you don’t link any subscriptions to music services, the Echo will always play Amazon Music Free and TuneIn radio.

The Amazon Alexa app, which is easy to use, is used to set up the device. On the app, you can change your Echo’s EQ settings, give it a name and place it in a room, or group it with other Alexa speakers that work with it. For example, you could make a group called “downstairs” and then tell Alexa, “Alexa, play music downstairs.” Your new multi-room Alexa smart set-up will do as you say.

Amazon Echo (4th Gen): Software and Connection

Even though this is a smart speaker with a voice assistant, you will probably use the app to control almost everything and get a lot done. Plus, you need it to set up the computer for the first time. You can control the volume, pair devices via Bluetooth, add a second speaker or subwoofer, set up multi-room groups, set alarms, choose whether the aux is being used as an input or output, and do a lot more with the app. You can also add more skills to your Alexa speaker by downloading them. It’s easy to connect the Echo (4th Gen) to play music.

All you have to do is take it out of the box, plug it into an outlet, and follow the instructions in the Alexa app, which is available for both iOS and Android. After you connect it to your Wi-Fi, you can use the personal assistant Alexa. When you turn on Alexa, a blue LED ring along the bottom lights up. This tells you right away whether or not the speaker heard your voice. The power input and an aux input are both on the back of the speaker. If you want to add this to an existing speaker setup, the base’s threaded universal mount will come in handy.

Amazon Echo (4th Gen): Alexa and Smart Home Skills

Amazon has taken the Zigbee radio from the Echo Plus, which was a smart speaker and smart home hub, and put it in the new Echo. Zigbee lets you connect compatible low-power smart home devices like door and window sensors and light bulbs directly to the Echo, so you don’t need a separate smart home hub. we used the Alexa app to connect a Zigbee door sensor to the Echo in less than a minute. When combined with Alexa Guard, this makes the Echo an ad hoc home security system. You can set up your lights to turn on if a window sensor is opened, or you can have Alexa send you an alert if it hears your smoke detector or glass breaking.

Even if you get an Alexa Guard-compatible DIY home security system, you’ll still have to call the police or fire department. We also think that Alexa’s routines are much more complete than what you can do with Google Assistant and HomePod. With Alexa, you can use the state of many smart home devices made by other companies to change how other smart home devices act. For example, we can set up a routine so that when the door sensor is opened, a smart light turns on, music starts playing, and Alexa says something to me.

Amazon Sidewalk is another smart feature that will be turned on later this year. It is a new long-range, low-power, low-bandwidth protocol that is meant to connect more devices in your neighborhood. So, if you leave your keys and Tile tracker at a friend’s house two blocks away, it will be easier to find them. Since the second-generation Echo, almost every Alexa smart speaker and a few Ring smart lights have Sidewalk. When it goes live, we are interested to see how it works.

Amazon Echo (4th Gen): Sound Quality

The Echo Studio is there for people who want the best sound quality. The Amazon Echo is a good choice for people who just want something that sounds good. This starts with what Amazon put in this fun ball. There are two 0.8-inch (20mm) tweeters and a 3-inch (76mm) woofer, so you get a lot of bass. On the factory settings, you have a warm tone, but vocals can be a little less clear and loud. The sound doesn’t get distorted when turned up loud, and it’s a good way to fill a room. The Amazon Echo sounds like a much bigger speaker than it is.

There are some simple ways to change the sound, but they are buried deep in the settings. Amazon could definitely do a better job of making it easier to control the sound on your devices. But when you do, you’ll find sliders for bass, mids, and highs. Even though presets for the equalizer would be nice, at least you can change them by hand. You can connect the Amazon Echo to the Amazon Echo Sub if you want even more bass. If you add one of these to a stereo pair, you will have a real room shaker. Still, the Amazon Echo sounds pretty good for something that costs only $100 and has all the smart features built in. Music might sound a little better on the Google Nest Audio, but the Echo will surprise you with how good it is.

Pricing and Availability

Amazon Echo (4th Gen) review

Both the Amazon Echo and Alexa can be bought around the world through Amazon’s own store. Even people who use “international versions” can get some services, if not full help. Not surprisingly, the Amazon Echo (4th Gen) is mostly sold on Amazon and has a regular price of $100. You can also choose between three colors: white, blue, and charcoal.

You can also buy them at the same price from third-party stores like Best Buy in the U.S. The best time to buy an Amazon Echo is during one of the many sales that happen all the time. Every year, Prime Day and Black Friday are the biggest sales, but there are other sales throughout the year, and Amazon isn’t afraid to offer big discounts on them.

Final Words

The Amazon Echo is the best smart speaker all around, and I don’t just mean how it looks. The 4th-generation Amazon Echo is interesting to look at because it’s a sphere, but it’s also one of the smart speakers for less than $100 because it has smart home networking tech and Amazon keeps making Alexa better. As we said before, the Sonos One is the best smart speaker when it comes to sound. But the 4th-generation Echo is a great choice if you want a smart speaker that does more than just play music. It can also act as a central hub for your smart home.


What all can the Amazon Echo 4th generation do?

Use your voice to play music from Amazon Music, Apple Music, Spotify, Deezer, and other services. With multi-room music, you can play music, audiobooks, and podcasts in every room of your house. Alexa is ready to help. You can ask her to tell you a joke, play music, answer your questions, play the news, check the weather, set alarms, and do many other things.

Is Echo 4th gen Dolby Atmos?

Under the fabric are a 3-inch woofer and two 0.8-inch front-firing tweeters, which allow the Echo to support Dolby audio (but not Dolby Atmos surround sound, like the Echo Studio, which has four drivers, including a 5.3-inch woofer).
