Sennheiser HD 428, HD 438 and HD 448 released

Sennheiser has rolled out a trio of new headphones in the form of the HD 428, HD 438 and HD 448. While the HD438 offers a more natural sound, the HD 428 will bring better lower frequency quality, targeting bass response as its main audience. All models will come with a gold-plated quarter-inch stereo adapter and a closed-back, around-the-ear design to insulate the sound for superior audio quality. Needless to say, the HD 448 will be the big brother among all three, and they are now currently available. Interested? The HD 448, HD 438 and HD 428 will retail for $130, $120 and $100, respectively.
