First spotted by TUAW, the shorter Lightning cable is Apple's second offering, adding to the regular one-meter long version sold as a replacement for the unit supplied with all compatible iPhones, iPads and iPods. Both retail for $19 in the Online Apple Store.
As for the in-ear headphones, not much has changed save for the remote control module with built-in microphone, which now takes on a shape first seen with the recently released EarPods. It appears that the update is merely cosmetic, as none of the hardware specs have been modified on the product page. The IEMs still carry a price of $79 in Apple's online storefront.
