Shenzhen, China — Horn Audio, a global manufacturer of audio products, today announced that it has developed a new white-box bluetooth headset that allows hands-free interaction with Alexa. The Horn Luduan V4 is the first product to be certified by Amazon on the Alexa Mobile Accessory (AMA) protocol,  and offers high-quality wake word detection with ultra-low power consumption.
