FEEL THE BASS, TUNED TO YOU™. Get ready to experience the patented, skull-thumping power of Crusher Bass — now combined with the ultimate audio customization of Personal Sound. You’ve never heard your music and movies like this before, because there’s never been anything like this before. Bought a few years ago but I don’t use them. Nothing wrong with them work well. I think these are an older model than the ones pictured. But same features.
