Monster isn’t exactly regarded as the most innovative force in tech, but it has decided to get in on the voice assistant game by baking support for a helper called Melody directly into their headphones.

Speak Music, which makes the Melody voice assistant included on this model of Monster’s Elements headphones line, has basically designed the feature around Siri’s musical deficiencies in supporting services other than Apple Music, something it doesn’t even do that well to begin with. Speak Music’s Chief Revenue Officer was VP of Product at Monster for a while so there seems to be some logic behind how this deal came to be.
