The simply-named 'A' speaker is a truly high-tech and wonderfully engineered speaker, developed by a group of engineers working out of the French capital Paris, that is designed to give you a headphone-like listening experience from a speaker package.
This speaker is capable of generating a very narrow beam of sound much like a laser creates a super-narrow beam of light. This allows you to blast sound directly into your ears from a distance without anyone else hearing it. The speaker is currently the subject of an Indiegogo campaign, and a pledge of $290 will get you a unit once they're ready to go.
This directional speaker offers endless possibilities thanks to its ability to focus sound and provide a headphone-like listening experience.
