Either you can get bluetooth headphones/speakers like Dan recommended, or you can attach a USB audio adapter to your computer. Before you buy one, make sure it works with OSX. For example, the Griffin iMic works for the Mac: [http://www.bhphotovideo.com/bnh/controller/home?O=&sku=797644&Q=&is=REG&A=details|link]. That will get your a 3.5mm headphone jack and a line in input too.
