Selling my Bose SoundDock Digital Music System I was using it in my dorm till I recently graduated works and sounds great! I contacted Bose after I bought it to get a longer cord so they sent me one over there 10 foot black cords off the black unit for free so can't complain! Needed a longer cord to reach the outlets in my dorm! It uses a 30 pin connector and you can buy a lighting adapter or even a Bluetooth adapter off Amazon if you wanted to use it on something else! Please let me know if you have any questions, I tried to take as many pictures as possible!
