[A]: Bad review

[Q]: The box of the headphones was not sealed and was missing a set of earpads. There should be several more pairs in this box. I hope to find at least one set. As far as sound quality, they are great, but if it is already used, you need to mention that fact. Thanks. James J Smith
[A]: Bad review

[Q]: The author seems to be out of his/her mind with this one. As another reviewer has noted, the book can be summed up in 3 sentences. But you get what you pay for. I got it for free by mistake, but still feel like i wasted my time and money on it. I'm going to keep looking though. Very disappointing. :-( Oh, one more thing, there was no cover page either. So even if they included a cover, someone would have guessed what is inside or where the chapter was.
