The HFI-680 headphones from Ultrasone provide crystal clear audio with a wide frequency in a compact and comfortable package. Ideal for monitoring vocals, tracking, mixing, and for portable or home entertainment devices, the HFI-680 can bring out the detail in your favorite tunes thanks to gold-plated 40mm drivers.
The headphones feature S-Logic Plus, an advancement to Ultrasone's S-Logic Natural Surround Sound technology that provides the same realistic, spacial audio soundstage in a more streamlined earcup. This technology also creates a reduction of sound pressure levels, giving you the same perceived loudness at lower volumes, which may help to reduce the risk of hearing damage.
In addition to being able to listen at safer volume levels, the HFI-680 offers reduced electromagnetic emissions. The ULE technology uses an MU metal bufferboard to reduce radiation by up to 98% compared to standard headphones. For users who spend a lot of time wearing headphones, this is a fantastic feature.
