The NEW EX29 features the same great isolation and comfort that has become legendary, with a host of new professional features that further sets the EX29 apart from other noise isolating headphones. A detachable premium cable results in greater mobility. Aircraft grade aluminum cable grommets provide superior stability and super-quiet operation. An 8' cable extension with 3. 5 mm stereo plug and 6. 3 mm screw-on type adapter expands the boundaries of connectivity. New High Precision Audio (HPA) drivers lead to improved fidelity and audio quality. A re-designed universal headband results in even greater comfort. The new Direct Sound EX29 continues its reign as the world's best noise isolating headphone.
