Ultrasone Pro 900 Over-the-Ear Headphones

Ultrasone Pro 900 Headphones


Recently, I have started to put more of a focus on using headphones in my office instead of speakers. I enjoy listening to music while working, but my cubicle neighbors don't necessarily appreciate the same type of music that I prefer. When a pair of  Ultrasone Pro 900 headphones became available for review, I obtained them to see how they would work in my setup and how they compare to my current reference headphones, the AKG K701's.
