Add stereo speakers with a subwoofer PLUS a cooling fan and say goodbye to horrid audio.17" Macbook Pro shown is NOT included (but will be listed separately).I did little more than try this out after purchasing new because my Macbook was a travel-only beast and I have not used it since I purchased this Macally. Just tested after being stored away for a few years and it is as fully functional as the day I purchased it.User's Guide, AC adaptor and USB connector all included. The Macally has a few rub marks on top from use, and some on edges (with a touch of paint) from closet storage.Features :USB Bus Powered Speakers and Cooling fanAC/DC adapter included to boost the audio performanceLine-in jack to support other audio or MP3 PlayersCompatible with any laptop computers 17" and underOn/Off switch for cooling fan and amplifierComplete 2.1 audio system with superior sound quality to accentuates your favorite musicUltimate thermal solution to cool down your notebookHigh efficiency and high performance Class D amplifierHigh quality speaker Drive: Right/Left 2" 2W x2, Subwoofer 2 1/" 10WSupports both USB 2.0 and USB 1.1System Requirements:Mac OS X 10.1 to 10.6 or laterWindows 2000/XP/Vista and Windows 7Any laptop computers with USB port, 60MB HDD space, and 512 MB DRAM system memory availableQuestions?
