Summary: The Creative Aurvana X-Fi Noise-Cancelling Headphones are well made, and the way they are packed into supplied zipped wallet is good. I connect these to my iPod and I would say they sound good but not they are exceptional sound quality.
Summary: -Positive: The sound quality is pretty good when using the battery power. With drained batteries the sound is a little bit dull but at least they keep working. The noise cancelling is alright. -Negative: With noise cancelling deactivated the insulation is average at best.
Summary: Sound is fantastic, although there is a lot of leakage so others around you can also hear. For me the fit was not good enough so I returned them and have gone for Bose QC3, however I do have a large head and the Sennheisers didn't fit either.
