Operating Your Headphones

The Ultrasone Performance 840 Headphones are designed for optimal audio performance in various environments. Their closed-back design provides excellent sound isolation, allowing you to concentrate on your audio without external distractions.

S-Logic PLUS Technology:

Ultrasone's patented S-Logic PLUS technology positions the sound transducer in a decentralized manner, creating a natural, three-dimensional soundstage. This unique design allows sound to reflect off the outer ear before entering the ear canal, mimicking the experience of listening to loudspeakers in a room. This reduces direct sound pressure on the eardrum, leading to less listening fatigue and a more spacious audio presentation.

ULE (Ultra Low Emission) Technology:

The Performance 840 headphones incorporate MU metal shielding to reduce electromagnetic radiation by up to 98% compared to conventional headphones. This technology minimizes potential health risks associated with prolonged exposure to electromagnetic fields, ensuring a safer listening experience.
