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.
