Thank heavens for the Sennheiser 4.50 BTNC Wireless. After all, while\u00a0there's really no arguing with wireless headphones\u00a0in concept, many\u00a0leave something\u00a0to be desired.\u00a0In most cases that "something" is consistent sound quality and proper noise cancelation. Sennheiser dutifully researched\u00a0all the\u00a0customer quibbles\u00a0and emerged\u00a0with these award-winning beauties. Accordingly, the HD 4.50 BTNC Wireless is a prime closed-back headset\u00a0that delivers superb audio, top shelf noise cancellation and supreme comfort anywhere, anytime.\r\n\r\n\r\n\r\nIn general, closed-back headphones already do a good\u00a0job at creating an insulated listening environment. However, that doesn't always mean outside noise can't get through and hinder the music--sometimes a little extra tech is required. That's why Sennheiser equipped the 4.50 Wireless with NoiseGard. It's an active noise cancellation technology that will effectively turn any surrounding environment into wallpaper (i.e. visual, not audible). Pair that sophisticated noise cancelation with proprietary Sennheiser drivers and the closed-back experience\u00a0and you're simply basking\u00a0in\u00a0rich detail and deep bass..\r\n\r\n\r\n\r\nNot only does the HD 4.50 Wireless deliver supreme fidelity, it does so with the absence of cables. As anyone who owns a pair of solid wireless headphones knows: once you go cord-free, you never go back. To make good on the hype, Sennheiser uses audio codec for transmission and New Field Communication to allow for seamless pairing with compatible devices. Enhancing those unfettered vibes are intuitive ear-cup controls and integrated microphones. Whether you're making calls or adjusting the volume, the process remains as beautifully simple as can be.\r\n\r\n\r\n\r\nThe HD 4.50 Wireless features keep coming strong. Giving the headphones some ergonomic\u00a0allure is an intelligent design that's as efficient as it is comfortable. The cushioned ear pads feel heavenly as they wrap your ears in a warm embrace. A foldable headband and adjoining case makes this portable gadget all the\u00a0more portable. On the purely visual front, the headphones rock the kind of\u00a0sleek, minimalist profile\u00a0that basically\u00a0never goes out of style.\r\n\r\n\r\n\r\nRounding out the many benefits of the HD 4.5 Wireless Headphones is a long-lasting battery. With NoiseGard turned on the battery lasts up to 19 hours. Turn NoiseGard turned off and the battery\u00a0won't quit for\u00a025 hours. Ultimately, the HD 4.5 Wireless represents the ongoing evolution of the immersive, cord-free experience. Slip them on and sink into music while the world becomes\u00a0wallpaper.\r\nCheck it out\r\nHave you subscribed to Man of Many? You can also follow us on Facebook, Twitter, Instagram, and YouTube.
