It can also let you interact with Amazon Alexa via an additional app download. You can choose to use your QuietComfort 35 headphones with your preferred assistant, or take advantage of them all if you'd like. Heading out for the night? Use your QuietComfort 35 to have Alexa send a message to your friend's Echo that you're leaving, have Google Assistant launch directions to the party, and tell Siri to take a selfie with everyone when you arrive.
