PROline technology and new design
PROline stands for Ultra Low Emission and means significant benefits for professional users as it is highly-developed and specially designed for professionals. The new design does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding.
PROline technology was systematically developed for professionals as they do spend half of their lives in headphones. Most headphone drivers today convert an electric signal into an acoustical signal, producing low-frequency magnetic fields. Medical research shows that these emissions can be hazardous to our health. In response, ULTRASONE developed a special MU Metal shielding to reduce the radiation by up to 98% compared to current headphones. The patented PROline (ULE=Ultra Low Emission) technology has stood the test of international review and is recommended by technical surveillance organisations.
S-Logic(TM) Natural Surround Sound
Through the S-Logic(TM) Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it's just like being in a live concert.
For this new technology additional equipment is not required. Take a pair of ULTRASONE headphones and you will be ready for the 3-dimensional sound enjoyment!
Safer Hearing
S-Logic(TM) Natural Surround Sound allows an up to 40% lower dB output (3-4 dB) for the same loudness sensation. This may significantly reduce the risk of hearing damage while ensuring hours of fatigue-free listening - an absolute must if you spend a lot of time in headphones.
Character
The 50 mm heavy duty driver produces an imposing sound intensity. Tight and powerful bass plus precise and detailed instrument place-ment is given. Combined with a lot of useful accessories PROline 550 will definitely find fans within bass players and drummers sector.
Due to professional needs and requests we implemented an additional function which enables you to fold these headphones for a compact storage and easy transportation in a suitcase. Thanks to its closed construction, external noise is suppressed.
