What is S-Logic Plus?

The basic Ultrasone S-Logic system doesn't as the name suggest, use any digital magic - the system is pure physical. The fundamental mechanic is a de-centralised driver positioning that, according to Ultrasone, means signals are reflected off the surface of the outer ear before entering the ear canal—a process more akin to listening on monitors than headphones. The 'Plus' in S-Logic Plus adds new precision dampening with micro-acoustic reinforcement which optimises the relationship between the driver, buffer-board and spatial parameters. Lastly S-Logic Plus incorporates re-designed, finely-tuned ear cups.
