You might recognize the new Widex UNIQUE 440. On the outside it looks very similar to the Widex Dream 440, and Widex Passion 440, but on the inside it sports a few significant changes. The new UNIQUE platform introduces "Sound Class Technology", which provides "automated classification of sound environments and optimal sound processing determined by the sound classes," four wide-input analog-to-digital converters and a new "Wind Noise Attenuation" that Widex claims provides dramatically reduced wind noise.
