ULTRASONE Pro 900i black

The sound of the PRO 900i combines the needs of both sound engineers and audiophile listeners.  The linear and dynamic sound represents the music authentically and accurately, which allows you to reliably evaluate the sound without any problems.  The convincing low range and silky highs of the 40 mm Mylar driver make music enjoyable, from modern pop and techno to hip-hop and the latest rock productions.  This is helped by the patented S-Logic Plus technology, which enables accurate and authentic reproduction of the stereo field.

Full frequency range
The PRO 900i emits the entire frequency range that can be heard by humans.  The reproduction range actually exceeds the limits of human hearing.  It reaches 6Hz and 42kHz frequencies.  This ensures that the headphones do not deprive you of any musical information in the audible frequency range and that you can enjoy the music perfectly.  You can also be sure that in professional use you can discover the smallest details in the entire frequency range.

Whether in a studio or in the living room, the extra-wide headband with artificial leather covering and velvet ear cushions ensure long-wearing comfort.  These ear cushions are easy to replace thanks to Ultrasone's quick connect system.  Bayonet locks keep the cushions securely in place.  Thanks to the use of robust materials, the PRO 900i guarantees a long service life.

ULTRASONE's unique ULE technology (Ultra Low Emission)
Most headphone drivers produce a low-frequency magnetic field when they convert an electrical signal into the acoustic signal we hear in the form of music.  ULTRASONE has developed special MU metal shielding, which we call ULE (Ultra Low Emissions), to reduce this radiation by up to 98% compared to conventional headphones.  This technology passed the test of international review.  ULTRASONE originally developed ULE technology for professionals, as they spend half of their lives in headphones.  With the increase in consumer demand, the ULE health-preserving technology has been included in all Ultrasone products.
