PNR - "passive noise canelling headsets Reduction" style headsets protect hearing by covering the ears and forming a seal against external noises. Much like hearing protectors - which is what they are at the most basic level - they buffer your ears from loud sounds and decrease the noise level that you hear. All headsets are passive in one way or another. Certain features of a unit can help or hurt the amount of passive noise reduction it provides. If the frame doesn't fit properly, it can allow extra sound through the ear seal, and reduce the noise reduction.

This is why wearing ear defenders such as ear plugs is quite necessary. Also avoid leaving the sander in one place all the time as it tends to damage the wood.

The risk is that most countries only allow you to bring in one carton. I still haven't figured out this rule since most duty free shops sell the cigarette cartons in 2 or 3 packs or have a buy one get one special. I have never been stopped by the customs officers but I do keep the duty free bag out of site in my backpack.
