When it comes to adding a voice assistant to a speaker or a pair of headphones, Amazon's Alexa has become the default choice for many OEMs, likely due to the openness and high adoption rate of the platform. Never one to miss a money-making opportunity, Qualcomm has decided to lend these manufacturers a hand by building a smart headset reference design, which features its very own QCC5100-series Bluetooth audio chip. With the Alexa app installed on your Android phone, once it's paired with these earbuds, you can toggle Alexa with a simple push of a button on one of the buds.
