IW-BTA250-Kit can be connected to Amazon’s Alexa

Pairing your Echo to a Bluetooth device is pretty easy to do:

First put your Bluetooth speaker into pairing mode.

Open up the Alexa app > Settings > tap your Echo device name > Bluetooth > Pair a New Device.

Once your Bluetooth speaker shows up within the app, tap it to connect and wait for Alexa to confirm the pairing is successful.

Amazon recommends placing the Bluetooth device at least 3 feet (1m) away from the Echo so that there's no interference. "When the Echo device is close to external speakers, it may be more difficult for Alexa to hear the wake word and other requests," Amazon says on its support page.
