5 of 5Does what it needs to. Monday, August 04, 2008 Bob from Dayton, Ohio
This device is simple and small. Works perfectly on a Macbook Pro's headphone port. I was skeptical at first thinking I would never be able to use my Z-5500 Digital speakers optically with my laptop. I was dead wrong, this device makes the Macbook Pro headphone jack emit a red optical light and then just plug in an optical cord and your golden. The only problem I am having is making the light go away when nothings plugged in. This is a laptop issue not really related to the device. Overall the item does what it is supposed to do. I suggest buying more than one since its cheap and shipping is the main cost of the item. They are easy to loose.
