Race Tracker Black Passive Noise Cancellation Stereophone

I was looking for a set of headphones to use with my iPod while mowing the lawn. I had used a set of headphones that hook over the ears, but I had to turn the volume up too high to hear over the noise of the mower.

I looked around at a lot of sites (including high-end audiophile sites) and Koss was often suggested as a good company with good products. Their no-questions guarantee was often cited as one of the reasons Koss is a good company.

I decided to try the QZ-5 headphones because they are relatively inexpensive.

As soon as I tried them on, I was impressed. They blocked out a lot of sound without even having them attached to a sound source. I couldn't hear the TV or the phone ring with the headphones on.

When I tried them while mowing I knew I had a winner. I could leave the volume level at the same level I would use if I wasn't mowing the lawn. The noise of the mower was not eliminated, but it was reduced significantly. It became a low hum in the background instead of a...Read more

I bought these from the manufacturer two weeks ago and I think these are the best things invented since the wheel! Therefore, when I found Amazon offered them I decided to get another pair for my office; and cheaper than than getting them from Koss direct! Anyway, they are the key to my survival because they TOTALLY screen out my next door neighbor's construction, another neighbor's dog (which is continually barking), and annoying leaf and lawn mowers. I now can concentrate on my studying while listening to all kinds (preferably classical) music. Anyone who wants the world to "go away" while trying to concentrate or sleep should get these. I found them to be extremely comfortable and the clarity of sound is excellent. They are superior and they will help to keep your sanity in this noisy world. :-)

Initially I bought these for NASCAR races. After getting an iPod I realized that mowing the lawn could be a little less painfull thanks to these headphones. I now bring them on flights to help me pass the time in quite comfort. These are the same as phones offered by Radio Shack but the Radio Shack product does not have the Stereo/Mono Switch that these have.

Sound quality is great - noise reduction is awesome. Reasonble price and free shipping. Hard to beat.
