Think all noise cancelling headphones are alike? Do you think there's basically just one use for head phones? Incorrect! There are many, many uses for head phones and - more specifically - for passive sound canceling headphones. Once you start using and wearing them, you'll find you won't want to leave home without them. Especially the small and compact earphone style.
Over the recent years, Bose has invented a series that was supposed to be the definition of passive noise canelling headsets, but they were just awful, static, and uncomfortable. This specific series was the "quiet comfort" headphones and they consisted of the QC, QC2, and the QC3. Now Bose has made a new addition to the series the Quiet Comfort 15. The QC15 should be put into its own series, because its way better than those that came before it. The QC15 is the definition of passive noise and they are wireless.
Wear ear defenders. Exposure to excessive noise can damage hearing. Noise reducing mufflers can be fitted to machines to lessen the noise health hazard.
Usually the lighter the headset, the less clamping you'll experience. And a lighter passive noise cancelling headset is just easier to wear anyway. So as you shop for the best headset, pay particular attention to the weight. Headsets can really vary in terms of weight.
Bass If you are the type of person that likes a lot of bass then these might not be the headphones you want, although the bass is there. It does not have as much bass as Bose.
Ear defenders- ear plugs and cotton wool won't suffice. Get yourself a set of ear defenders as continued use without them could potentially cause lasting and irreversible ear damage.
