Professional Active Noise Cancelling (ANC) Technology. Our improved ANC technology significantly reduces noise to help you focus on what you want to hear. ANC works both with and without the audio cable and is great for reducing noise during long trips on a plane or in places with city traffic. Superior Sound Quality. The superior sound quality of the E8 is 25% stronger than that of our earlier E7 model. The 100dB give a deep, powerful, and crisp sound -- making your overall listening experience just that much better. Upgraded Soft Ear Cushions. The over-ear cushions on the E8 are designed with a 90° rotation axis to help the headphones fit snugly to your head. Our new lightweight cushion material features magnetic absorption, which helps improve comfort and sound quality over long periods of time. Built-in Microphone and Bluetooth. The E8 provides you with a high-quality microphone—making calls with these headphones just that much better. The Bluetooth function supplements this nicely with the ability to detach yourself from wires, giving you the ability to make hands-free calls. Use the buttons on the headphones to turn the volume up/down or to skip/rewind a song. Shipping: We ship FROM US to the Lower 48 States only (Does NOT include Hawaii or Alaska).
