Summary: Have only been using these for a while. Comes with a plug adaptor that is compatible with the dual plug in hook-up in most airline seats. The switch that screens out background noise seems effective. Length of ear covering devices adjusts, so it is not uncomfortably tight. Reasonably priced.
Summary: Frankly, for under $50.00 I didn't expect much. That being said, these Panasonics are as comfortable, and may even sound better than my expensive Bose headphones. The sound when the noise-canceling switch is thrown is what I would expect from a $175.00 price point.
Summary: First I need to set your exectations, if your looking for headphones to give you complete silence then just skip these headphones. However, if you work in a noisy office or have a lot of white noise these will bring the noise to a tolerable level, by themselves.
