In theory, Sony’s newest wearable sounds promising. The Xperia Ear is a single Bluetooth earbud that lets you dictate messages, get weather updates and smartphone notifications, and carry out other little tasks just by talking to it. It’s like having an Amazon Echo in your ear, except with far fewer skills and third-party integrations. 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.
