After it rolls out, you’ll be able to adjust the EQ via voice commands for Alexa or manually through the Alexa app or on-screen controls with the Echo Show or Echo Spot. There are a variety of ways you can ask Alexa to change the EQ, like “Alexa, turn up the bass,” “Alexa, set treble to maximum,” and “Alexa, reset equalizer.”
