SR125x | Headphones
Grado Labs developed our proprietary SpaceBlack Polycarbonate to absorb stray sonic vibrations. Those unwanted secondary impulses can 'muddy' the sound, and we're all about purity. The SR125x uses ultra-high purity long crystal oxygen-free copper voice coil wire, and an eight-conductor cable. That's scientific. Get onboard the SR125x if you want space, you want black, and you want the only mud hitting your ears to be Muddy Waters.
