Allen and Heath is a well known company known for there top of the line Dj equipment. As of late they have come out with an upgraded headphone model entitled the Xone Xd 53.
The Xd 53 headphones are powerful, they pack a huge 53mm driver that allows them to produce exceptional sound quality at very high volume levels. They also have a solid build construction and large ear cups which help to isolate any background noise around you.
I personally own a pair of these bad boys and can honestly say they sound amazing
THese headphones will run you about $150 -$200, which is about half of what you would pay for some Beats by Dre Studios.
