Sony's NW-S705F Noise Canceling MP3 player is now on sale in the U.S. for about $199 for 2GB version and $169 for 1GB. You may remember when Crave reported on Sony's announcement of this player back in October. The big hullabaloo is that the NW-S705F has active noise-cancellation integrated into the player. Before you get too excited, the active noise-cancellation system will still require you to use Sony's proprietary earbuds. Even though the noise-canceling circuitry is in the player, microphones located on the outside of the earbuds are necessary for the function to work properly. The other catch is that despite its support of DRM-free MP3, WMA and AAC files (as well as Sony's ATRAC), you'll still have to use the abysmal SonicStage software for loading music from your computer.
Those drawbacks aside, noise-canceling is a great way to save your hearing during those subways commutes. Plus, the NW-S705F includes an FM tuner, a 50-hour battery life, and a unique shuffle function called Time Machine that will pick a random year and play a selection of songs released in that year.
