|Skullcandy Crusher Evo Headphones from JD WilliamsGet ready to experience the patented, skull-thumping power of Crusher Bass – now combined with the ultimate audio customization of Personal Sound by our partners at Audiodo. You’ve never heard your music and movies like this before. Because there’s never been anything like this before. Skullcandy Crusher is the original, one-and-only immersive sensory bass experience. Turn the slider down for more mellow bass. Turn it up to really rattle your bones. Plus, Crusher Evo features audio quality improvements over original Crusher so you’ll experience an even broader range of deeper, richer bass. No one’s hearing is the same. That’s why Crusher Evo features Personal Sound. By taking a quick, real-time test on the Skullcandy App, you’ll create a Personal Sound Profile that is stored on your headphones to optimize sound levels just for you. Audiodo technology in the Skullcandy App analyzes the hearing in your left and right ear, then automatically adjusts the audio to optimal levels for your specific hearing. So you’ll experience sounds in your audio that you’ve never heard before. Crusher Evo features built-in Tile finding technology. If you ever misplace your headphones, you can easily ring them from the Tile App. So what might have seemed lost, is now quickly found. You don’t have time to plug in your headphones every time you turn around. That’s why Crusher Evo is engineered with a full 40 hours of battery life. Plus, whenever you get low, the Rapid Charge feature gives you an extra 4 hours of listening time from just a quick, 10-minute charge.
