Purchase criteria: How to compare Echo models

All devices in the Echo range offer Alexa support and pretty much the same commands and features – with the exception of the Echo Show 5. However, there are some differences that may change your experience with the device, we’ve listed the main ones below:

  • With or without screen
  • Sound quality
  • Device design
  • Price

We will detail each of these topics throughout the section. By following these tips you will find the ideal device for your needs.

With or without screen

The Echo Show is the first device in the line-up to feature a 5.5-inch touchscreen with HD resolution. The device also features a 1MP camera with HD resolution and a 4W speakerphone on the back.

The device is ideal for those who have surveillance cameras in the internal or external areas of the house, as you can view the images through the device. Another possibility is to make video calls through the Echo Show 5. You also have access to multimedia content.

Sound quality

The devices in the Echo line are smart speakers, for this reason it is essential to evaluate the sound quality of these devices at the time of purchase.

The Echo is the one that stands out the most in this sense, as it has premium sound quality with 360º projection through two speakers: 3″ neodymium Woofer and a 0.6″ Tweeter. These two speakers have Dolby sound quality.

The Echo Dot has only one speaker with 1.6″ and the Echo Show 5 has a 4W speaker. It is worth mentioning that all models can be connected to external speakers via a 3.5mm cable or Bluetooth connection.

Device design

You can find Echo devices in different shapes and sizes. The Echo has a cylindrical shape just like the Echo Dot, the difference between them is that the former is larger and the latter is compact.

The Echo Show, on the other hand, resembles a tablet, with a rear speaker stand.

Another difference is the tone, there are options in black, gray, white or blue (only the Echo Dot). The choice is related to personal preference, but the lighter the device, the more it will attract attention.


Of course, in addition to all the criteria already mentioned, the price of each needs to be taken into account when choosing your Echo. Obviously, the models with more features end up costing more.

Therefore, the Echo is the most expensive of the family, followed by the Echo Show 5 and the Echo Dot. You should weigh price against other criteria before deciding which Echo is right for you.

Tip: You can install the purchase in up to 12 interest-free installments on your credit card.
