Pretty much everyone is in agreement that when listening to music on your iPhone the sound quality pretty much sucks. The volume isn’t very loud and the music starts to get muffled and distorted. There are simple ways around this without buying a $150 iHome or whatever kind of amplification system is out there, I personally enjoy using a ceramic bowl or glass cup. (it works wonders!) Another interesting way comes via JWT in Brazil who came up with the idea of using a standard magazine to promote the use of Coca-Cola FM. A nifty way to promote listening to music and getting your app more downloads and listens, pretty smart stuff.
