Well today I have completed my travel pack. Which now consists of Mophie juice pack air and Shure 115m+ headphones. The juice back is amazing case it is soft rubber but also includes a battery pack to extend the life of the iPhone battery. The Shure headphones are also great sounding and are in ear sound isolating so you don’t have to crank up the sound all the way to get good sound. The sound response of the headphones are pretty good and clear and has good bass response. Also these headphones have volume control for your iPhone to do all the sound control and voice commands.
