Foldable, closed-back headphones featuring natural surround sound.

Character
The PRO 650 comes in the specifically designed PRO Box including 2 detachable cables and a spare pair of earpads. The earpads are easy to change (speed-switch-technology). As with all Ultrasone PRO models, the detachable cables make it easy to choose the cable you prefer. The closed-back PRO 650 uses high-class gold-plated drivers. In combination with the design, PRO 650 offers a spectacular open 3-dimensional balanced image with a maximum of transparancy.

ULE-technology & PRO design
PRO headphones have Ultra Low Emission (ULE) technology with significant benefits for professional users. PRO headphones also have a unique design; the PRO appearance not only distinguishes the professional line but also allows a higher degree of transparency in combination with the spatial sense and understanding, due to more ear anatomy area.

To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal that you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organizations. Ultrasone originally developed the ULE-technology for professionals as they spend half of their lives in headphones. But due to grand requests the, ULE-technology has now been integrated in other Ultrasone headphone lines.

S-Logic Natural Surround Sound
Through the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head into the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived-it's just like being in a live concert. For this new technology, additional equipment is not required. Take a pair of Ultrasone headphones plus your sound device and you will be ready for the 3-dimensional sound enjoyment.

Safer hearing
S-Logic does not only create a Natural Surround Sound. S-Logic allows, at the same time, a reduction of sound pressure levels by up to 40% (3-4 dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage.

Mix Down

Posted by Texhoma Bob from Texas on Jan 6, 2009

Experience w/product: I own it

Reviewer's Background: active

Reviewer's Play Style: blues, jazz, & my own

These are great for mix downs. They are not a headphone I would use for recording. They sound like crap coming off a line level mic out. This will over drive the headphones on the bass end and cause a crackle. My advice is don't use them unless your going thru a mixer.
