Sony ULT WEAR Wireless Noise Canceling Headphones with Dual Noise Sensor Technology (Black)Feel the incredible power of sound and bass with the Sony ULT WEAR Wireless Noise Canceling Headphones. Press the ULT button and find yourself at the center of your music wherever you go. Feel like you’ve dived into the front row of the concert, and turn the moment on with the ULT POWER SOUND series. Built for music lovers, it produces powerful deep sound designed to make your heart tremble. Prepare to feel the bass. Select from two different types of bass-emphasized sound: ULT1 for deep, low-frequency bass, or ULT2 to experience powerful bass. Enjoy precise, punchy, high-quality sound that gets you as close to the original recording as possible, with a specially designed 40 mm driver unit and Integrated Processor V1. When an original music source is compromised, it loses the high-frequency elements that add detail and richness to a track. Sony’s Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that’s closer to the original recording. Tailor sound to your personal preference. Choose from a variety of pre-sets to match sound quality with the genre of music you're listening to. Or create and save your own using the equalizer feature on the Sony Headphones Connect app. With two microphones in each earcup and Dual Noise Sensor technology to capture ambient sound, you can block outside noise everywhere you go, so the only thing you hear is your music. The Integrated Processor V1 helps to eliminate external sound, with a low processing delay to make the noise canceling more effective than ever.Bundle Includes:Sony WHULT900N/B ULT Noise Cancelling Headphones (Black)Energy Core LCD 20W PD 10000mAh Battery Ultra Pack
