from the review...... Headphones site
Looking to fully maximize the audio performance of your beloved AKG k702, k240, or k271 headphones? Supreme high-end cabling kings Cardas Audio in Oregon have designed and manufactured this AKG replacement headphone cable at HeadRoom's behest. Expect vastly improved tonal/timbral definition, an even more expansive and deeply-layered soundstage image, and a renewed sense of smoothness and detail throughout the entire audible frequency range.
The standard 'Lifetime' Cardas Audio manufacturer's warranty covers any defective cords for as long as you own it.
Is this real? .. or just "merchandising"
