These are the first headphones I have bought so have anything to compare them to. I didn't find them as good as most of the reviews I read but I think, for the money, they are OK. I have to say though that I did try some very expensive ones in the shops and so my expectations may not be realistic.
Excellent book. Bought it along with my new mini iPad and although that contains an online manual, the book has provided invaluable help and useful tips. Very easy to understand and would recommend to anyone who has never used an iPad before.
