Alexa is finally getting an equalizer feature, letting users adjust EQ settings with commands like “Alexa, decrease the treble.” It’s nice feature that I’m honestly a bit surprised the company didn’t introduce a while back. After it rolls out over the next couple of days, you’ll be able to satisfyingly tell your Echo, “Alexa, turn up the bass.”

The full features are only coming to the U.S. for the time being, making it possible to adjust different bands between -6 db and 6 db on the standard Echo, the Dot, Plus, Show and Echo Spot.
