Yurbuds new Ironman series earphones ($50) are designed to work in even the most extreme conditions and activities. If you regularly work out, run, or train while listening to your iPod, you’ve probably encountered the problem of ill-fitting earbuds that fall out with every unexpected head turn. The Ironman series, partially designed by a triathlete, aims to do away with that problem by using extra soft medical-grade silicone, which provides a snug fit and comfort for extended listening periods. Neodymium drivers provide solid sound quality while a sweat-proof, water-resistant design allows for use in the toughest environments or during the most intense workouts. The earbuds come with an extra set of Intense style covers as well as a red nylon carrying case and Ironman trading cards.
