Alexa, turn it up

Alexa, turn it up: Fine-tune your Echo’s sound for higher (treble) or lower (bass) frequencies. Just say “Alexa, reset the equalizer,” or “Alexa, turn up the treble.” Or open the Alexa app and go to Devices (lightbulb icon) > [your Echo] > Device Settings (gear icon) > Audio Controls, then use the sliders to adjust.
