German headphone manufacturer Ultrasone has announced a new flagship for their HFI line. An open-back pair titled the 2400 with 40mm gold-plated drivers and all sorts of other bells and whistles.
The claim to fame is Ultrasone’s S-Logic technology. I’m sure there’s all sorts of fancy science behind it, but it basically means that the drivers are mounted off-center. This allows the sound to bounce around your head for a bit, instead of being pumped directly into your ears. Supposedly, it gives the effect of a much more three dimensional musical experience. Other high points include a reduced sound pressure level, meaning less strain on your ears. Also, the “MU metal shielding” reduces the amount of magnetic radiation “as much as 98%” So if the only thing holding you back from buying a pair of headphones was the lack of proper radioactive safety regulations, these might be the pair for you.
They fold up into a convenient size, and have a detachable, straight cable. And the technical schematics all say the right things to make a audiophile-level pair of headphones.
