The Ultrasone Performance 820 (Black) is an entry-level model boasting a strong but lightweight build.  Its centerpiece is the patented S-Logic® Plus technology, which combines precision-dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner.  With its decentrally-configured transducers, S-Logic® Plus technology promises natural three-dimensionality and fatigue-free listening and working. Regardless of your ear size, the Performance 820 is easy and comfortable to wear, thanks in no small part to the design of the bycase leather earpads.  While moderately tight to ensure proper isolation, the headband is designed to adapt to individual head shapes, ensuring a near-universal fit. Extremely comfortable velour ear pads containing memory foam for a perfect fit are available as accessories (sold separately).

These headphones are fitted with 40mm PET sound transducers. They are available in black, black and white, and black and red color schemes.

The Performance 820 comes with a 1.2 m (3.93 ft) locking removable cable with in-line mic and remote and a 3.5mm gold-plated jack. The bayonet connector means you can quickly change to a different cable of your choice (sold separately).  A transportation bag is also included.
