The Ultrasone Performance 840 Headphones combine the benefits of the company's S-Logic Plus signal processing, natural surround sound, and ULE MU metal shielding system with soft-touch lacquer and glossy accents in black for an elegantly finished closed-back design. This model's sound signature was designed to provide agile bass using a 40mm dynamic transducer with a PET membrane and NdFeB magnet to deliver a frequency response of 10 to 25,000 Hz with into a 32 ohm load at a maximum SPL of 96 dB.
To ensure comfort for hours of continuous use, the headphones feature an adjustable metal headband and high-quality protein leather ear pads with memory foam that adjust themselves to fit your head and minimize external noise. The unit's ULE MU metal shielding technology reduces the amount of radiation received by the headphones by up to 98%. They come with a 3 m detachable cable with a bayonet connector and a 3.5mm audio jack. They also come with a gold-plated 6.3mm screw on adapter as well as a Neoprene storage pouch. A short 1.2 m cable and velour and memory foam ear pads can be purchased separately.
S-Logic Natural Surround Sound

Combines precision dampening with micro-acoustic reinforcement, allowing the driver, buffer-board, and spatial parameters to complement one another in an optimal manner
Uses a funnel-shaped arrangement for the transducer, which allows it to be positioned further away from the ear
Ultra Low Emission MU Metal Shielding
Uses a metal shielding to reduce the radiation generated by the headphones by up to 98%
Memory Foam Earpads
Conforms to the listener's ears to ensure a snug and comfortable fit
