What a stroke of genius! These “Acoustibuds” slip over a pair of cheap earphones to make them into a pair of expensive noise-isolating headphones. The guys who run CES agree, awarding them an innovation award at the show this year.
They also promise to stick in your ear better than standard earbuds. The flexible ‘wings’ hold the bud in place “even with perspiration and extreme physical activity”, claims the manufacturer. Not bad for $13 (£8.70), especially if you’ve got one of those awful phones with a proprietary connector meaning that you have to use the rubbish provided earbuds.
