Among the accessories are various cases, mounts, batteries, headphones, and a screen protector. The leather cases will allow users to store their ID and credit cards with their phones, as well as their cash. The aluminum mounts will allow you hands-free access to things like videos, emails, and whatever you can do with your phone that doesn't require your hands.
The batteries will allow you to bring extra juice on the go, the screen protector will protect your screen from your greasy fingers, and the headphones will give you good, wireless sound. All the accessories are scheduled for release alongside the Galaxy S4, so look for them in mid-April. Check out the full press release below for more details.
