The new K175 represents the culmination of decades of refinement-from the transducers, to the porting, to the fit and finish.

With the K175, it's almost as if you were sitting in front of a pair of great reference monitors-transparent, defined, and uncolored.YOU'VE NEVER HEARD BASS LIKE THISWhen you're serious about editing and mixing your music, you're looking for more than thumping bass in your headphones, you need nuanced low frequencies. The K175 offers 40mm transducers-the largest in their class-to create greater low-frequency extension and detailed bass reproduction. This makes it easy to define each and every instrument you're hearing.BUILT TO LASTAfter decades of the strictest product standards and most rigorous of testing regimens, quality has become synonymous with the AKG name-and these headphones are no exception. From intensive driver stress tests, to an 80,000-bend-cycle for cables-even an exaggerated drop test-we put our headphone designs through the gauntlet, so you can count on them for years to come. All of the critical pieces are metal, including the hinge, guaranteeing they last through heavy use. Additionally, the cable is replaceable, further extending the life of your investment.TAKE THE STUDIO WITH YOUWith a completely foldable design, made possible through an innovative, three-axis hinge, the K175 can easily be collapsed and transported in tight spaces, like a travel bag. The design minimizes the exposure to damage that comes with the demanding mobile lifestyles of musicians, producers, and audio engineers.
