The Aurvana X-Fi headphones are a set of noise-cancelling over-ear from Creative. The X-Fis are priced at $300, which puts them in the price range of other noise-cancellers. Though they have a similar price, the X-Fis have more features than the typical pair of noise-cancellers. For example, most noise-cancelling headphones integrate music playback with their cancellation feature: you the headphones on to get noise cancellation and music, you switch them off, and the music turns off along with cancellation. Unfortunately, this also means dead batteries kill your music playback. The X-Fis, on the other hand, keep noise cancellation separate from music playback. You can switch cancellation on and off, and dead batteries just means you have to listen to your music without cancellation.
