Spatial sound and fatigue-free listening thanks to S-Logic® Plus
Both the sophisticated tonal balance and patented S-Logic® Plus technology provide unique reproduction of your favourite music. The decentralised arrangement of the sound transducers creates a spatial sound normally only expected from high-quality speakers. A broad stereo platform with excellent depth graduation allows listeners to completely immerse themselves in the music. This spatial impression is created by the S-Logic® Plus design, which reflects sound more frequently before it reaches the inner ear. This design principle also ensures fatigue-free music enjoyment and protects the hearing. With S-Logic® Plus,compared to conventional headphones, a lower sound pressure level is necessary at the same volume level (3 - 4dB).
Design inspired by Ultrasone Edition
When developing the Performance series, Ultrasone drew inspiration from the design of the highly acclaimed Edition 8. For example, echoes of the Edition 8’s unique lines can also be found in both of the new Performance models. The headband pad, with a laser-engraved Ultrasone logo, is an attractive highlight. The ear cups of the Performance 860 are contoured with black and silver, whereas the Performance 840 has a completely black finish. To perfect its elegant look, Ultrasone uses high-quality materials that guarantee long-lasting satisfaction.
The best sound – for people on the move
The trend of wearing large headphones on the go remains unbroken. Thanks to hinged ear cups, headphones in the Performance series can be easily stored, meaning they can provide excellent sound even when travelling. All models come with a stylish neoprene soft case for transport purposes. People who are always on the go profit especially from the closed design of these models, which significantly reduces outside noise.
Excellent wear comfort
Whether at home, in the studio or on the go – in addition to sound, comfort is one of the most important criteria for developing headphones. Ultrasone have developed a new headband pad that adjusts perfectly to the shape of the head. For the first time the cushioning has been made of memory foam, which not only boasts excellent acoustic properties, but also adjusts perfectly to the contours of the head. The breathable material allows air to circulate despite the closed-design principle. The special foam is covered with particularly soft and durable high-quality protein leather, guaranteeing hours of unique wear comfort.
In addition to the neoprene soft case, a 3-metre cable with 3.5mm jack and 6.3mm jack screw-on adaptors is included with both Performance models. The cable can easily be changed with a bayonet fastening; other cables, like a 1.2m mini-jack variant with headset functionality (remote control cable and microphone), are available as accessories.
