Immerse yourself in your favorite music, video, and other audio without the distraction of outside noise with Sony MDR-NC200D digital headphones. Designed for the true audiophile, Sony built these headphones for canceling outside sound while enhancing the quality of the audio you’re playing on your media listening accessories. By blocking 98.2 percent of ambient noise, Sony MDR-NC200D headphones reduce strain on the ears by allowing you to focus solely on your music instead of struggling to hear over outside sound. These Sony MDR-NC200D headphones feature a headband-style headphone design and operate on one AAA battery for wireless power, offering up to 22 hours of battery run time and working with all of your favorite media playing accessories. Further enhance your listening experience by personalizing it with one of three modes: air travel, train travel, and office. These Sony headphones use artificial intelligence to automatically determine which canceling mode is best for the environment you’re in, the type of noise present, and the type of audio to which you’re listening. Selecting the right mode is simple thanks to different chimes for each option, as well as a green LED status indicator light and user-friendly controls. Get high-quality, crystal-clear sound without distracting outside noise thanks to the 40mm driver units, as well as full digital amplification and a digital equalizer that ensures the highs are as high as they can be and the lows are as low as possible for deep bass tones and full, rich, in-ear audio. Thanks to the ample padding, the ear cushions are comfortable enough for long wear, even during a lengthy trip. They’re also compact and collapsible so you can easily take them on the road with you, and they won’t put pressure on your ears no matter how long you wear them. These Sony MDR-NC200D headphones also work without the noise-canceling option engaged, and they’re compatible with a wide range of electronics and devices, including TVs, phones, laptops, music, software, video and DVD players, and other accessories. Plus, the cable is detachable and replaceable, making it easy to stow away in your luggage when traveling, as well as simple to replace if damaged. These stereo Sony MDR-NC200D headphones also feature a monitor button so you can quickly and easily turn off the noise-canceling function if you need to have a quick conversation, take a phone call, or check on something. Plus, they come with an adapter designed specifically for airlines so you don’t have to invest in extra equipment or worry about compatibility. Weighing just 6.4 ounces, these Sony headphones won’t weigh you down when traveling, and they have an adjustable headband so you can get just the right fit for long-wearing comfort. This noise-canceling headphone connects to your electronics and other devices using a 6-inch cable and a 3.5mm connector on both ends.
