The Sennheiser CX 680 Sports are in-ear headphones designed for those who like to exercise while listening to music.

Keeping in-ear headphones firmly in place can often be a bit of a problem, especially when you’re working up a sweat, so the earpieces on the Sennheiser CX 680 Sports can be fitted with a pair of flexible rubber ‘earfins’ that fold inside the curve of your ear and help to keep them secure.

Sennheiser includes three sets of earfins and three sets of earpieces in different sizes with the Sennheiser CX 680 Sports, so you should be able to find a set to fit.

The cables on the Sennheiser CX 680 Sports are made out of Kevlar, which is both rugged and water-resistant, even in heavy rain. Two cables are provided – a short one for when the iPod is held in an armband and an extension cable that has a built-in volume control so that you can keep the iPod tucked safely inside your pocket.
