If you have been looking out for some real good noise-cancelling headphones which do not burn a hole in your pocket, the HN-900 from Creative has to be your best pick. The company has had more than decent reputation in this niche and more so this one has integrated microphone for making cell phone calls unlike those of Bose and others. It’s juiced by one AAA battery which gives you about 40 hours of active noise-cancellation.

Besides the company has also announced its pricey noise-canceling model called the Aurvana X-Fi 2 which is priced at $200 and adds virtual surround technology. Also it is worth noticing that the Aurvana offers better noise cancellation but doesn’t feature the integrated microphone unlike its poorer sibling.
