HFI-15G portable headphone lowers listening fatigue

German company Ultrasone has released the smallest headphone in its HFI line, the HFI-15G. The open-back supra-aural design features a decentralized driver position that is claimed to widen the sound-stage by directing the waves to the outer ear, instead of straight into the ear canal. The company lists a frequency range of 20Hz to 20kHz, with a sound pressure level of 96dB. The 40mm Mylar drivers are configured with an impedance of 32 Ohms.

The headphones are fairly light for the size of the driver enclosure, weighing in at 85 grams without the cord. The company claims its S-Logic technology reduces the sound pressure levels by up to 40 percent for the same perceived loudness, lowering fatigue during long listening sessions.

The HFI-15G carries a suggested price of $110, and will be available from several resellers including Guitar Centers and Moog Music.
