Like Night and Day!!

Need to handle them with care.

Comfort is fantastic. Feels like I don't have them on my head.

Soon as I put these puppies on , the sound was fantastic! I could tell the difference from the headphones I was useing. The bass was well rounded. Now it will be a pleasure to mix my songs.

Simply Awesome!!

Quality is awesome, they fit comfortable, you won't even know they are on your ears.

Best features include volume control. Although they are not noise canceling these headphones do block out a substantial about of noise sounding you. I'm a church musician and our drummer is not caged in. Before these headphones I could hardly hear myself in the monitors. Using this along with Rolls personal More Me Monitor station has made a huge difference

Item was a great purchase for me.

They're made really well. I love the constructions.

They take a good beating on the bottom end. I mean your hear evey note in the 808 or your bass line, but the mids are to colorful. Not made for mixing if you ask me, because they make it seem as if the vocals are out in front of the mix, but when you bounce your mix down to refference it the vocals are super low.

It's simmple plug in the cable and they work without any batteries.

They seem like a cheap attept at the beats by dre. I love KRK I own 2 differentr types of their monitors, as well as a sub woofer. These to me are for producers only not good for mixing vocals. not quite as good as the beats by dre but at half the price you will be some whate happy.
