Here are the Pros and Cons.
Pros: Sound is beautiful and crisp, perfect for good techno or any high wav file music
Headphones come with an App that you can use to customize the sound and equalize it however you want to. There are some preset templates for vocal, club, pop and other types of music.
The right side of your headphone is a touch pad that you can use to pause, skip to the next song, raise and lower the volume and answer the phone if you're hooked up to your iphone.
They are WIRELESS so no more clutsy moments with your headphone wire.
Different levels of surround sound going up to 180 degrees really make you feel like you're in a club or concert.
They pause when you remove them
Headphones are made of cushiony, comfy patented leather
Although high tech, you don't have to be a tech geek to figure this gadget out
Cons:
They're made of metal so can be heavy on your head and can give you a headache
The touchpad on the right headphone goes bizurk if you happen to be laying on your right side
You can't stretch or retract them
Be careful, they're very powerful, the first day I got these I went a little crazy and my ears were ringing the next day.
They are rechargeable but the battery life was not as long as I had hoped(about a day and a half)

These are definitely worth it for me, but then again they were a gift.
