Sony's Xperia Ear is not the hands-free assistant I wanted

In theory, Sony's newest wearable sounds promising. The Xperia Ear is a single Bluetooth earbud that lets you dictate messages, get weather updates, smartphone notifications and carry out other little tasks just by talking to it. Sony also promises a long-lasting battery that can endure a full workday of talk time with the included charging case, so you can have the assistant ready for your commands all day. Unfortunately, the Xperia Ear simply doesn't do enough to justify its $200 asking price. Sony's Xperia Ear is an intriguing device -- in theory. It's a single Bluetooth earpiece with a built-in assistant that's always ready for your voice commands, and will recite your smartphone notifications as they arrive.
