S-Logic™ Natural Surround Sound
Through the S-Logic™ Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it’s just like being in a live concert.

For this new technology additional equipment is not required. Take a pair of ULTRASONE headphones plus your sound device and you will be ready for the 3-dimensional music enjoyment!

Safer hearing
In addition, the HFI-650 is easy on the ears: The S-Logic™ Natural Surround Sound System allows an up to 40% lower dB output (3-4 dB) for the same loudness sensation, thereby the risk of hearing defects may be reduced enormously.

Reduced magnetic field emissions
Like all the ULTRASONE headphones, the HFI-650 has a strongly reduced radiation. The standard version LE (= Low Emission) offers a reduction of up to 60% in comparison with ordinary headphones.
It is certified and recommended by Technical Surveillance Organi-
sations and Consumer Advice Centers with certified low magnetic field emissions.

Character
ULTRASONE´s closed-back headphones HFI-650 provide an excellent shield to the “outside”. Experience the new standard with complete isolation of a closed-back pair of headphones with the honest sound of open ones. They create an extraordinary balanced, natural and precise sound image. The HFI-650 daily proves a worldwide achievement in music production, in recording, television and broadcasting studios. The high-class gold-plated drivers are very sensitive and provide a maximum of transparency.These are superior characteristics every consumer wishes to find with a pair of headphones.

Due to customer enquiries we implemented an additional function which enables you to fold back and up the individual earpiece without removing the headphones from your head. Due to this folding mechanism, these headphones can be compactly stored and easily transported in a suitcase.
