Excerpt: Ultrasone is a relative newcomer to the U.S. headphone market. Founded in 1991 and based in Tutzing Germany, Ultrasone has provided the European market with products for the past 19 years. Fortunately for us, the brand is beginning to catch some mainstream attention here in the U.S. and, if they keep making products like the HFI-2400, we think that trend will continue upward.
Conclusion: The Ultrasone HFI-2400 sound incredible and, at $299.00, they outperform headphones that cost much more. Their balanced, engaging response and tremendous dynamic capability are the stuff that audiophiles drool over. We found them extremely entertaining and satisfying. We would encourage you to give the HFI-2400 a listen and consider putting the money saved into a headphone amp to raise them to their full potential.
