Boom Boom connects to your mobile device or PC via Bluetooth or a headphone jack. It plays just like a regular speaker, with rich sound and a portable, durable design that makes it easy to carry anywhere. But it can also talk to you in a variety of languages — like Siri, if Siri were super well-traveled and multilingual. It cheerfully greets you when you turn it on, and it'll tell you when to charge the battery. You can also speak to it. Use it for conference calls instead of a speakerphone, and Boom Boom optimizes the voice quality.
