Many people simply aren't satisfied with the quality or fit of the earbuds that ship with their iOS device. Fortunately, there are some great third party options. You can find custom-fit earphones that cost well over $1,000 to reasonably priced solutions under $100. Wired and wireless headphones and earphones are available, with and without microphones. You can also add a pair of portable stereo speakers.
Some of the coolest accessories are those that extend the viewing experience of iOS devices. You can give great on-the-spot presentations with a pocket projector or get a big screen experience on an airplane with a sunglass style display.
