these be my first Sennheiser Headphones . I purchase they base upon the glowing review for they sound . I just also buy a pair of Sony 7506 headphone at about the same price range . the Sony 's blow these out of the water . the 7506 's have deeper bass , better imaging , extend treble , and be more sensitive . they also seem to mate better with my Yamaha receiver for impedance purpose . the Sennheiser hd-280 's will give you better sound than less expensive headphone , but both the Sony 7506 and v700dj model be overall better in sound , sensitivity , power handling , and distortion .
