The headphones use Ultrasone's proprietary S-Logic Natural Surround Sound technology to provide a realistic soundscape, creating the impression that you're listening to high-quality speakers that are actually several feet away. This technology also produces the same perceived volume levels at a lower dB rating, allowing you to set the volume on your player a bit lower, potentially reducing the risk of hearing damage.
