Answer Wiki. The Amazon Echo and Amazon Echo Dot are stationary devices (they need to be plugged in). The difference between them is that the Amazon Echo has a much better speaker built in, while the Dot is intended for use with an external speaker via line out/Bluetooth. The Dot is much smaller and cheaper so if you want Alexa in multiple locations, it's the best option.
As a result, the Echo has quickly become one of Amazonâs best-selling products, even more popular than its Kindle line of e-readers. If the original Echo was Amazonâs Trojan Horse to get into your home, the new Echo Dot is Amazonâs army coming in behind it. Itâs smaller and half the price ($89.99 vs. $179.99), yet has all of the same far-field voice recognition technology and voice control capabilities as the larger Echo. You donât need a full-size Echo to use the Dot â it is a fully standalone device.
