The AKG Q701 reference-class premium headphones represent a momentous partnership with AKG and one of the most accomplished musicians of the 20th century: Quincy Jones an American icon whose productions include the best-selling album (Thriller) and single ("We Are the World") of all time. Quincy has received an unprecedented 79 GRAMMY nominations and 27 GRAMMY awards, more than any other living artist. It stands to reason that the headphones he puts his name to must be nothing but the very bestand the Q701s are the most accurate and responsive headphones AKG has ever produced. Reference denotes a class of audio equipment that imparts little to no change to the input audio signal, producing a huge, airy, three-dimensional sound. The over-ear headphones feature revolutionary flat-wire voice coils that create a spacious, dramatic soundstage with precise 360-degree imaging and outstanding transient response. two-layer diaphragms similar to your professional studio counterparts offer sparkling high-frequency sound and accurate bass response. Additionally, a high-performance neodymium magnet system makes the headphones heat-resistant for minimal distortion at any listening level. The Q701s deliver pinpoint imaging with unmatched realism. Says Quincy, "This is the best quality sound I've heard in headphones, ever. And I'm proud my name is on them."
