The new iPod nano’s small size and clip make it perfect for active lifestyles, but extra headphone cord length gets in the way. Innovelis’s Cord Shrink ( stores the extra cord length so you can focus on your workout, says Eric Wengreen, CEO of Innovelis.

Constructed of a rubber material, Cord Shrink attaches to the new iPod nano’s clip and allows a person to store unwanted headphone cord length. Cord captures prevent the cord from inadvertently unwinding.

Storing the extra cord length prevents the cord from snagging on runners’ swinging arms and becoming tangled. The US$14.99 Cord Shrink is only compatible with the sixth gen iPod nano.
