If you want to shut the world out next time you're talking on your mobile - and save them from being bored by one half of your conversation - you could perhaps invest in one of these.




The Pentaphone certainly makes for an interesting idea, although I'm not exactly sure how mobile it is:P

Gizmodo reports:

"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"
