CONS:

1. Let's get this out of the way.  It's heavy.  Your head won't be used to it but after you wear this for a few days and get past a little neck pain, your muscles will strengthen and then you get all the benefits.

PROS

1. Unlike a lot of headphones, these are really hard to break.

2. Unless you have special studio phones, these are absolutely without a doubt the best headphones ever. The quality is superb and you won't find something better for this price.

3. These headphones tune out the whole world. Get ready for hours of enjoyment.  It's like being at a concert or listening to a fine symphony or opera.

4. It's Koss so it has a lifetime warranty with no questions asked.  I have a lesser pair that have been destroyed twice (one time I jerked the cord standing up and it stopped working and the other time a vacuum cleaner tore the two side cords off) and Koss had a new pair sent to me and I didn't lie about how either were damaged.

5.  All I have to say: Koss all the way.  Stay with this company faithfully and the dividends will be enormous.
