Koss QZ-2000 Active Noise Reduction Stereophone Review

Koss QZ-2000 Active Noise Reduction StereophoneI fly 100k/per year, and happened to sit by a young lady from Japan about 3 years ago who let me try her Sony noise reduction headset. I was surprised how effective it was and how much noise and stress you are exposed to when you are flying. I immediately tried a Brookstone noise reduction headset I got in the next airport, which I used with my portable CD player - and was surprised how much it contributed to arriving more comfortable, relaxed and effective. However, it was bulky, heavy enough to hurt my ears after being worn for 30 minutes or so, and began to come apart. I tried the Bose NR headset - which is great - but still a little bulky and heavy. This year a got the Koss QZ-2000 - and it's the one to get. It works as well as any of the others, but takes less space in your luggage and is so comfortable you can wear it from London to San Francisco - no problem. The combination of the QZ-2000 and my Compressor Personal Jukebox (now I don't need to carry CD's) means I have relaxing noise reduction and my choice of music anywhere.

GN1200 Smart Cord 6IN Coil Direct Connect part #l 88011-99 Review

GN1200 Smart Cord 6IN Coil Direct Connect part #l 88011-99I love the sound of these headphones.I use them on a Mitel VoIP system.They seem fairly rugged and I've had no problems.I work in a fairly noisy server area, and received favorable comments from listeners it's much easier to hear me now.Negative: the description failed to mention the need of an adapter plug. I had to call the seller to find the one to use.The cost of the adapter was another +$20.After getting over the anger, I was okay.

Q:Electronics Noise Canceling Headphones Review

Q:Electronics Noise Canceling HeadphonesI got these headphones from a co-worker and I had never heard of the brand before. I was coming off using a pair of sure noise canceling headphones that cost me $150. I thought that those were great headphones until I plugged these bad boys into my i-Pod and started jamming. I literally love these things! Plus in the package you get all of the adapters you will ever need and a very nice headphone pouch for traveling. I let a friend of mine that was an avid listener to his i-Pod and he used the $300 Bose noise canceling headphones listen to these ALTEAM noise cancelers and he couldn't even tell the difference. These are a really great headphone if you want the quality of the expensive guys but you don't want to spend that much. Every time I see somebody with $300 headphones I chuckle a little, knowing that I have the same quality for less than one third of the price!

Product Description:
Reduce and even eliminate the noise from airplanes, train rides, or noise at home or abroad. Q:Electronics acoustic noise-canceling headphones employ Active Noise Canceling technology so you can actively reduce and even block ambient/outside noise. What makes these headphones better than any others? Soft, high quality cushioning makes for a pleasant listening experience. The ear pieces rotate for a better fit. With such a good fit and soft, light-weight design, you hardly notice you're wearing headphones! Active Noise Canceling requires power to run and batteries. Other headphones store the batteries in a box attached to the cable which weighs down the cable and pulls the headphones down making them uncomfortable to wear. Batteries for the Q:Electronics Noise-Canceling headphones are stored in the headphones themselves making cable management much easier. Other noise canceling headphones will not work unless the noise canceling function is turned on. However, the Q:Electronics headphones will work regardless of whether you have the noise canceling featured turned on or off. You can enjoy better and louder sound because the Q:Electronics headphones have volume control built into the headphones. Adjust the volume to your liking with these headphones and sit back and enjoy your music. If you just want to reduce the noise around you, remove the cable from the headphones and turn on the noise canceling feature. Listen to the noise around you dissipate and even disappear as you relax with your favorite music. Specifications Frequency Response : 20 ~ 20,000HZ Driver Unit : 40mm mylar cone (Special), CCAW coil Active Cancelation: 20~1000Hz,better than 10dB between 150-300 Hz at max. cancelation Impedance : 30 ? ± 15% Max Power Output : 100 mW Noise Reduction : 70~1,200Hz Auto Distortion : 0.05~1% Power : AAA x2 Batteries (not included) Battery Life : Approx. 50 Hours Jack : 3.5mm Plug Weight : 120 grams
