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 SR125e uses ultra-high purity long crystal oxygen-free copper voice coil wire, and an eight-conductor cable. That's scientific. Get onboard the SR125e if you want space, you want black, and you want the only mud hitting your ears to be Muddy Waters.

"… the '125 is a neutral, detailed, and warm sounding headphone overall, with extended frequency extremes, wide dynamic range, and the ability to sound natural at a wide range of volume levels. Based on my experience with the budget and top-of-the-line Grado models, I remained convinced that the SR125 represents the greatest sound quality per dollar in the Grado range."
