These tough earphones have been designed by Ultimate Ears - the choice of the world's top touring musicians. They won't fall off while you're exercising thanks to the easy-to-use, shapeable ear loops. Made from durable, sweat-resistant materials, your earphones can stand up to even your toughest workouts. With five pairs of soft silicone ear cushions from XXS to L, you won't have to worry about getting a long wearing, comfortable fit - even if you've got small ears. They've been tuned for extra bass to keep you rocking. A protective hard case easily fits into your pocket or your bag while you're on the go or at the gym. And you can use your earphones with your iPod, MP3 player or any laptop with a 3.5 mm jack.
