Price is good, too.I also have a Senheiser HD497 and I prefer this one's sound quality over HD497. Deep bass, nice treble. The only thing I don't like about this headphone is the size. It is not flexible enough. So if you have a big head, it starts to hurt your ears after a while. If you have small or medium size head, this would be a perfect pair of headphone.

input with options: Title: Loyalty Marketing: The Second Act Review: I have read Brian Woolf's two most recent works on loyalty marketing. For many, the world of loyalty marketing and its results may seem incomprehensible, or worse yet, unquantifiable. However, in his new book, "Loyalty Marketing: The Second Act", Brian has conveyed the importance and power of building real loyalty with the consumer. His frequent use of case studies spanning several industries, illustrates and quantifies the benefits of building an effective loyalty program and putting it to work in even the most competitive and mature of markets. In today's business environment, it's not enough to simply attract new customers. The silver bullet for success is the ability to retain those customers through the years to come.Whether you are a proprietor or charged with the marketing initiatives of a large retailer, Brian's real-life examples and insights captured in his latest book, will give you the competitive edge to secure profitable and loyal customers.

EA Sports has done an excellent job with the franchise, but I must say that I'm very disappointed with this game. This game is garbage compared to what I was used to. There's no such thing as a fast break because whenever you run down court with a player, like Allen Iverson, any CPU player can catch up to you and prevent the fast break, even if they're supposed to be much slower, someone like Ben Wallace. Where's the realism in that? Other complaints are, the buttons don't react quick enough, the computer only shoots outside shots (unless it's wide open), and rebounding is impossible in the game. I wouldn't buy this if I were you. EA Sports and the NBA Live Franchise just lost a long time fan. Is this product review negative?

input with options: Title: Yuck. Review: Actually another word came to mind but need to write a G-rated review. Starts out in severely distorted mangling of song such that only a few notes each time play then stop, wham, restart, second track is full of scratches of needle across grooves or tape equivalent of running a nail across mastering. Then degenerate rendering of usually beautiful Bond theme. Could get no further into this. Among the 5 worst of several thousand CDs I have heard. Now I do not even want to stream the flick.
