Press statements

  • quoteFor: a punchy, precise bass; a high degree of comfort; and excellent build quality.

    SFT 2/2010

  • quote... thanks to its open but circumaural design and spacious, vivid sound, the HFI 2400, which weighs a mere 300 grams, also looks good in a computer studio. Thanks to its S-Logic technology, it also sounds remarkably different and reveals lots of new nuances after a brief familiarisation phase.

    Beat 6/2010

  • quoteThe Ultrasone displayed the best sound quality of all the headphones tested.

    MacUp 10/2010

  • quoteThe headphones involve the entire outer ear in the listening process. As a result, the sound is much more natural than with traditional headphones or with in-ear phones.
