The EC100 and WR100 in-ear models are aimed at sporty types, or those with "active lifestyles": the adjustable ear clips should keep them securely in place, and the WR100s have the added benefit of being water-resistant should you be going for a long jog or cycle in the rain.
For those with a more relaxed lifestyle, the CB25 EarBuds (shown) are available in four colours to match the iPod nano: orange, blue, green and black. They're supplied with three sets of silicone ear tips.
And finally, the EB50 metallic EarBuds come in a choice of three "vibrant" colours: blue, green and pink metallic.
