ALTENG noise cancelling headphones are engineered to sound better, be more comfortable and easier to take with you. Put them on, suddenly everything changes. Your music is deep, powerful and balanced, so quiet that every note sounds clearer. Even air travel becomes enjoyable, as engine roar gently fades away. No matter how noisy the world is, it's just you and your music-or simply peace and quiet. Active Noise Cancelling Technology: Build in ANC circuitry continuously measures, compares and reacts to outside noise-then cancels it with the opposite signal to make quiet sound quieter and music sound better.
