Creative Technology Ltd today announced the new Creative HN-900 headphones, which utilize active noise cancellation to reduce ambient noise by up to 85 percent. The Creative HN-900 headphones also feature an in-line microphone and switch for convenient one-click voice communication on the iPhone, and 40 mm Neodymium drivers and gold-plated plugs for outstanding audio playback. Dual-mode usage allows active noise-cancellation for up to 40 hours by a single AAA alkaline battery or in passive mode without power. Creative today also introduced the Aurvana X-Fi 2 Noise-Canceling Headphones, which utilize active noise cancellation to reduce ambient noise by up to 90 percent, and feature X-Fi audio technology for improved sound quality and a virtual surround sound effect that is ideal for watching in-flight entertainment. The Creative X-Fi Crystalizer utilizes algorithms to make any digital audio sound better by intelligently and selectively restoring the highs and lows that were lost during MP3 or other compression. The Creative X-Fi CMSS-3D virtually transforms stereo headphone playback into the more immersive listening experience of a surround sound speaker system. Users can independently select noise cancellation, X-Fi Crystalizer, X-Fi CMSS-3D and volume with convenient controls on the headphones. All of the technologies can be enjoyed together for up to nine hours from two AAA batteries. The headphones can also be used without audio technologies in passive mode.
