Koss Has Balls Asking This Price For These Headphones!.......2006-02-15
Ok lets face it, wireless headphones certainly haven't been perfected yet and any wireless headphones that operate on radio frequency (like these headphones) are going to have some kind of hissing and reception noise but I expected a little more at this price from Koss considering they're suppose to be state of the art in headphones! For Koss to have the balls to ask $300.00 (at Koss.com $400.00) is totally ridiculous! These wireless headphones are no better than wireless headphones that cost anywhere between $50.00 - $100.00. The sound quality is a little better than cheaper wireless headphones but what sinks these is the reception. I don't recommend these for this price, it's a total rip off! The only benefit to owning these is the lifetime warranty.
Hiss and break-up.......2001-01-11
If you like quiet music or wish to be mobile then these are definitely not for you.
Unless the volume reaches a certain level, then there is just too much hiss. To drown out the hiss you either need to increase the volume sufficiently that you cannot hear anything else in the room (that's not very high since these are closed earphones), or play different music.
Even when you are within 2 meters of the transmitter, moving your head just a couple of inches can result in signal break-up.
If you are prepared to sit still and listen to rock music at the right volume then the sound quality really is quite good. However for over $200 more flexibility is expected both in terms of mobility and clearity.
In mono the hiss goes away, as does the signal breakup (within 10 meters). However, you are paying for stereo headphones.
The batteries don't last long (maybe 4 hours) and to recharge them you must connect a cable between the headphones and the base unit and push a switch on the base. With some other makes you only need sit them on a stand. Also the batteries cannot easily be swapped. So if you want to listen for 6 hours, or you forgot to charge them, you'll just have to wait until they are recharged. You cannot just insert a new battery.
They are a bit on the heavy side.
Something I do like is that there is no tuning dial for the radio signal, so cannot accidently detune them.
Classical listeners will be disappointed.......2000-10-18
Listening to classical CDs throughout the house was my goal in purchasing these cordless headphones. General reception is pretty good, although it does fade in and out somewhat as I move through the house. Most annoying, however, is a constant background hiss, which distracts from the high quality sound I hoped for.
Your satisfaction with this product will probably depend on your listening preferences. Most radios stations and many pop-type CDs would come through just fine. Discriminating lovers of more quiet music will not be satisfied.
What a Great Combo.......2000-06-17
Koss JR900 Cordless Stereo Headphones are the best in cordless. I've shopped around in many stores looking for such a bargain. I can't find one. The average price was 500.00. These headphones can work throughout my whole house! I just plug them into my computer and listen to MP3's while I clean. There great and very comfortable. I will encourage everyone to buy these well made Headphones.

Very slick set-up.......2007-03-30
For the money, this audio shelving system will not dissapoint most. It is very clean looking and rather easy to install. We had to make some minor adjustment due to our home being CBS construction and do not have the ability to screw the brackets into the studs. The one draw back was the design of the cable management system. It only allows you to pull the cables from the very bottom or top of the brackets and not in the middle where the shelves and thus the components sit. There is a little wire showing but for the money it is worth it.
Product Description
The Video Separator is a signal booster and splitter that is used to take video input from a single source and direct it to eight video outputs for monitors using analog signals. The signal boost obtained by using the VS98A allows you to not only split the signal but to extend the distance so that you can send the signal to about 210 feet. (Your average VGA card, combined with a standard VGA cable, can send a clear VGA signal approximately 25 feet.) This makes public broadcasts from a single computer very feasible. If you want to display the same information on many monitors at once, such as in a classroom environment, or at a demonstration, this product performs incredibly well. Bandwidth is the term that is used to describe the signal capacity of these units. In general, bandwidth is directly proportional to the amount of data transmitted per unit of time. Specifically, in analog signals, bandwidth is the difference between the highest-frequency and the lowest frequency components of a signal. For example a voice telephone signal has a bandwidth of 3000 Hz (or 3000 cycles per second), where an analog TV signal has a bandwidth of approximately 6MHz (or 6 million cycles per second) which is approximately 2000 times greater than a simple voice phone call. These units have a bandwidth of 200MHz (which is 150 million cycles per second) and that is 25 times greater than a simple TV signal. This huge bandwidth allows for the transmission of large amounts of information at a very high rate of speed, and thus you can use the very high-resolution setting of 1792 x 1344 in 24 or 32-bit true color mode at a refresh rate of 60Hz. 8-PORT 200 MHz VIDEO SPLITTER
