The Pentaphone is the brainchild of Austrian designer Robert Stadler and is intended to offer a stylish means of conducting a conversation on your cellphone without being distracted by ambient noise. As you might have guessed, this product is only a concept piece at the moment, and it is likely to stay that way until people become comfortable with the idea of looking stupid under a giant helmet-like wooden dome.
