The HD 428 is part of a series of boldly designed headphones designed to be an extension of consumers lifestyles.
From the Manufacturer
Focusing more on the lower frequencies and offering a powerful bass response, the Sennheiser HD 428 on-ear headphones sound as good as they are styled, with a dark rubber coating providing a rugged, sporty design. The closed-back design blocks ambient noise for use on-the-go, or at your home studio. The rubberized outer shell features a unique crosshair design, which adds to the durability of the headphones.
You'll get powerful bass-driven stereo sound thanks to the headphone's neodymium magnets, and the single-sided cable stays tangle-free, making it easy to use and store. For perfect sound on a home hi-fi system, the HD 428 comes with a gold-plated 6.3 mm stereo adapter.
