Noise reduction and low cost but bulky

Date of Review:  Sep 6, 2000
Review: In my opinion, you can put on the QZ99 and "almost" be completely shut out from outside noises.

These headphones are designed for noisy environments such as an airport or racetrack. They are ideal for someone who has a radio scanner and...

Heavy, but Effective

Date of Review:  May 25, 2004
The Bottom Line: I would recommend these headphones only for indoor use. They are great for blocking out noise at home or, say, on a plane. They might be too heavy for some.
