Whether you've had yours for a while or it's a new device, Echo Dots are popular smart home devices that come with Alexa and are made by Amazon—but they do lack in sound power. To amp up your Echo Dot's sound, it's a great idea to connect it to your soundbar for a higher quality sound experience.

To connect an Echo Dot to a soundbar, you can pair the devices over Bluetooth or connect them with an AUX (3.5mm) cable. Both connection types are simple and straightforward, and only take a few minutes to set up.

Once you connect your Echo Dot to your soundbar, you can enjoy hands-free music, audiobooks, alarms, information, and more with a robust set of speakers. What could be better?

Different Methods for Connecting an Echo Dot to a Soundbar

When it comes to connecting your Echo Dot to your soundbar, there are two options: wired or wireless. If you want to make a wireless connection, you'll want to use Bluetooth via WiFi. If you want to have a wired connection, you can use an AUX (3.5mm) cable.

These are the most common ways to connect your Echo Dot and your soundbar, and most soundbars are compatible with, coming with either Bluetooth, an AUX Out port, or both.

How to Connect via Bluetooth

Soundbar to Receive via Bluetooth

The Echo Dot can use a Bluetooth connection to pair with your soundbar, as long as your soundbar is Bluetooth-enabled. Most soundbars are, so this is an easy way to connect your Echo Dot to your soundbar. Here's how to get started:

  1. Make sure your Dot is set up properly and connected to your home WiFi network
  2. Put your soundbar in Bluetooth pairing mode
  3. Open the Amazon Alexa app on your smartphone
  4. Navigate to 'Main Menu', and then 'Settings'
  5. Select 'Device Settings'
  6. Select your Echo Dot by name
  7. Select 'Bluetooth', which will bring up any current pairings
  8. Select 'Pair A New Device', and you will see your soundbar appear
  9. Select your soundbar to pair it

Once this is finished, your Echo Dot and your soundbar will be connected wirelessly through Bluetooth. Your soundbar will be your Echo Dot's speaker as long as it is on and as long as both devices are connected to your network.

If for some reason you want to disconnect your soundbar and your Dot's Bluetooth wireless connection, you will follow the same process:

  1. Open the Amazon Alexa app on your phone
  2. Navigate to 'Main Menu', and then 'Settings'
  3. Navigate to 'Your Devices'
  4. Select your Echo Dot by name
  5. Select 'Bluetooth', which will bring up your current pairings
  6. Remove your soundbar by selecting it, then clicking 'Forget Device'

This method can be used to remove the Bluetooth connection between your Echo Dot, as well as with any other device of yours.

How to Connect via AUX (3.5mm) Cable

Aux Cable.

Echo Dots can also be connected to your soundbar through an AUX (3.5mm) cable. This is because Dots are equipped with an AUX output port, and most soundbars have an AUX input. This is an easy, wired connection that is possible with a soundbar, as long as your soundbar and Dot are near one another (or you have a long AUX cable).

Here's how to make your wired connection through an AUX cable:

  1. Get a 3.5mm AUX cord. Make sure it is a good length
  2. Open up your Amazon Alexa app on your smartphone
  3. Select 'Devices' from the Main Menu Settings
  4. Select your Dot by its name
  5. Select 'AUX Audio', then 'Line In or Line Out'
  6. Connect your AUX cord to your Echo and your soundbar

Now you are connected through your AUX (3.5mm) cord, and any streaming or listening on your Echo Dot will come through your soundbar as long as both are powered on. If you ever want to listen to your Echo Dot through another device, simply disconnect the AUX cable from your soundbar.

What if the Soundbar Only Has a Digital Optical Input?

Optical Connector

In some cases, like the higher-end Sonos Playbar (on Amazon) which is discussed more below, you may not have an AUX input on your soundbar, and if you want to make a wired connection, you may be wondering if you can use your soundbar's digital optical input.

There is a big difference between AUX audio and digital optical audio, and it's most ideal to stick to the same inputs when connecting devices. Trying to connect an AUX input to an optical audio input may result in a less-than-satisfactory audio experience.

Auxiliary inputs support an analog audio connection, and digital optical inputs support a digital audio connection. Digital and analog audio signals are completely different. In short, an analog signal is continuous, and a digital signal is non-continuous.

You may find that there are cables that can help you make this connection. However, your best bet is to just go with a Bluetooth connection instead. If you don't have access to a Bluetooth connection, you could test out an AUX to optical digital cord, or you could find another speaker to connect with your Echo Dot.

Some Soundbars have Alexa Built-in

As Amazon Alexa has become more popular, many soundbars are now equipped with Alexa. Some soundbars say they are Alexa compatible, but some actually have Alex built-in. This means that you can access Amazon Alexa on your soundbar by itself, in addition to through your Echo Dot.

You can enjoy hands-free listening, streaming, watching, and more on soundbars with built-in Alexa. If this is something you're interested in, here are a few top choices to look at on the market now.

Sonos Beam

Sonos creates some of the best soundbars on the market, and the Beam is a front-runner in the mid-range price point, which includes built-in Amazon Alexa.
