Ultrasone Performance Series 840 Headphones

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 (neodymium) magnet to deliver a frequency response of 10 to 25,000 Hz with a 32-ohm load at a maximum SPL of 96 dB.
