What's Amazon planning to reveal – Alexa in the ear?

Is there a wireless earbud that answers to the name Alexa in your future? Amazon is staging an event Wednesday in Seattle to introduce its fall lineup of devices. At last year's event, Amazon introduced 70 products, including updates to the Echo speaker line, a microwave that answered to Alexa and a DVR for cord-cutters. This year, CNBC reported, an Alexa earbud could top the list. Apple dominates the earbuds market with the help of Siri.
