Home & Studio - The new HFI-450 includes the sound technology of the legendary HFI-15G.

The closed-back HFI-450 offers the same powerful, clear sound reproduction that Ultrasone users have come to expect. Entry-level HFI-450 headphones are specifically for audiophiles on a budget who still want the famous Ultrasone sound for home and studio.

Ultrasone S-Logic Natural Surround Sound

It's just like being in a live concert! Ultrasone's S-Logic Natural Surround Sound creates a 3-D sound field with proven psychoacoustic principles. No additional equipment is required. Sound reflecting off of the outer ear helps us to localize its source. The Ultrasone S-Logic system directs sound to the outer ear before it enters the auditory canal, creating natural 3-dimensional sound. Instead of trying to squeeze a band (or an entire symphony orchestra) inside your head, Ultrasone HFI-450 headphones immerse you in a rich, natural musical environment. And they do it without any artificial echo, time delay, or digital processing.

Safer hearing

Ultrasone S-Logic not only creates natural surround sound, it also reduces sound pressure levels as much as 40% (3-4 dB), while maintaining the same perceived loudness. Listening at lower volumes without losing the perception of volume increases listening pleasure while reducing the risk of ear damage. You'll have hours of fatigue-free listening. (However, that's not an excuse to crank it even more. To prevent hearing damage, Ultrasone advises you always to listen at lower volume.)

Even at very low volume levels, Ultrasone HFI-450 headphones still deliver the same spacious sonic effect, so you to hear every sound as though you were there when it was recorded. For even greater safety in long listening sessions, Ultrasone employs a special MU Metal shielding (ULE), for Ultra Low Emissions that reduces electromagnetic radiation by 98% as compared to conventional headphones.
