Output: Positive


Input: Consider Input: I've noticed very little degrading of the sound, if at all, and this is rare in most extensions. The cord is thicker than usual for both the positive and negative polarities - a separate wire for each - and I'm quite pleased with this, will perhaps get another because of its thickness. I now have great headphone sound within a twenty-foot range - just what I was looking for. Even if you don't need 15-feet of cord, I would recommend this over the shorter 10 foot cords where the wiring is about half as thick and not likely to hold up over time...I subject all my electronics to heavy use. Plus, the best extensions for Grado headphones go for $40, and I'm quite satisfied saving over $30 by having this one.

Output: Positive


Input: Consider Input: My wife and I built a hybrid timber frame home using this book as a guide. Although we have construction skills, this book was invaluable in guiding us through the process. We can't wait to build another. We highly recommend this book to anyone considering a timber frame house.
