Bought the PlayStation 4 1TB slim for Christmas. Once I understood the instructions (Im a bit slow when it comes to instructions) setting up the transmitter and earphones was quite easy. Get so main compliments on these! Decided to go with these after reading the reviews. The only apparent metal is the wire to adjust them. suitabke price and arrived when expected as well Im not sure I will be reading the next book in the series, but this book provided me with a light and pleasant read, and for that I am appreciative. It is great as a watch and a HR monitor but nothing else Cleaner and easier to label. In my 43 years I have assembled countless pieces of furniture, exercise equipment, toys, gadgets and everything else under the sun but this was one of the most frustrating things I had to put together.
