Amazon Echo Detailed Review

December 19, 2016

The Amazon Echo is a voice-activated portable Bluetooth and Wi-Fi enabled speaker that gives you rich sound around the house. It integrates a personal voice assistant named Alexa. Maybe you have heard of popular voice assistants like Siri, Cortana, and Google on your tablet or phone. Well, the Amazon Echo is Amazon’s answer to these voice assistants. It connects to your Wi-Fi to access cloud services and to also communicate with other devices on your network. When Amazon launched the Amazon Echo in November 2014, it was just a speaker for playing music. You could issue commands like: “Alexa, play some Christmas music.” Then it could connect with its cloud sources and fill your house with ambient Christmas sounds.

Over the past several months, Amazon has made significant improvements to the Echo software; it now has a variety of amazing capabilities. Amazon Echo can read audiobooks, play your favorite podcasts, and control other smart devices around your house. It even knows about local businesses around your home; you can ask ‘Alexa’ where to go for grocery shopping, the menu at a particular restaurant, and stream music from services like Spotify or Pandora. It has transformed into a semi-intelligent Artificial Intelligent machine – it is no longer just a Bluetooth music speaker! If you plan on automating your home, the Amazon Echo is a must-have accessory for any smart home. Let’s dive into detailed specifications.


Amazon Echo consists of a 23.5cm tall cylinder speaker with a seven-piece microphone array. Its weight is approximately 26.9 ounces (1045 grams), though it may vary slightly depending on the manufacturing process. The Echo isn’t exactly portable like other portable speakers, as it needs to be plugged in and connected to Wi-Fi at all times. It requires constant power and a connection to the internet to provide you with its intended services.

The Echo has two buttons on the top, for ‘mute’ and ‘listen,’ the top ring rotates to raise or lower the volume. It also comes with a traditional remote for controls like play, pause, forward, and backward. If you would prefer controlling it using your smartphone, there is Amazon Echo App for that purpose. It is even easier using the app to control radio stations than asking Alexa to do it for you. Towards the bottom of the Echo is a 360-degree speaker that fills your room with quality sound.

Technical Specifications

The Amazon Echo includes an ARM Cortex-A8 processor, with 256MB RAM and 4GB of storage. It has no internal battery. The Echo works with dual-band Wi-Fi 802.11a/b/g/n and Bluetooth 4.0. The Alexa app is compatible with Android, Fire OS, and iOS devices and also accessible on the web via a browser. When purchased, the box includes the Amazon Echo, a quick user guide, and a power adapter.
