Simple but effective 
2008-05-11
The Koss VC20 volume control simplifies the volume control and the clip holds the control module at a handy position.

I had purchased a volume control at Radio Shack that worked reasonably well -- for about two months, when it broke. So I was looking for something of a bit higher quality. Good reviews here convinced me that this Koss product was just what I needed. Sadly, this is not for anyone who is even remotely an audiophile. When you turn the volume down it dramatically attenuates the high end, so music sounds not just quieter but also has a much narrower dynamic range. This item would probably last much longer than the cheap Radio Shack control, but the sound quality is completely unacceptable. So why do many people on Amazon give it high marks? I have no idea, unless they are listening to books on tape or something else that requires only low audio quality.
Works great! 2008-05-02
I bought this so that I could easily control the volume on my iPod Touch during bike rides and it does the job perfectly.
AMAZING DURABILITY!! 2008-04-18
What can one say about this simple, but much needed accessory??
-KOSS VC20 volume control-best one I have ever used.
Ever use an accessory rotary volume control (if you can find one)??
They usually work for a week, get a speck of dust inside, then become choppy or silent!
Most headphones are furnished with a rotary volume control,
the better headsets, of course, usually have the better quality control.
However the controls drop dead, just before the headphones do....
I mow acres & acres of lawns all season long-lots of dust & pollen.
I use the KOSS VC20 every day (going on two years)!!
If it gets dirty, a tiny squirt of Deoxit-and it springs right back!!!
Amazing durability from an $8.19 component!
Won't boost volume 
2008-04-06
Whereas this device will allow you to adjust the volume, the range is limited from no sound to the volume you'd have without it. I had gotten the [apparently mistaken] impression that it would boost the volume for headphones which had low volume for some sources (like Zune, IPod), but that does not appear to be the case. Since you can always lower the volume on the source (mp3 player, etc.), I'm having a hard time seeing the value of this device - except that in some cases it might be handier to have an inline control.
Excellent!

A very handy little gadget especially when your working out and you'd normally be fumbling for the volume control on your arm band.
worked great...for a day 2008-07-14
I purchased this based on the recommendation from Amazon about what a great add-on this product is. It was great - the one time it worked. Unfortunately, I needed to leave the country (on vacation) so I didn't get a chance to return it the time limit. I'm glad it was less than $10 but I guess I got what I paid for. Maybe I got a reject from the factory because the other customer reviews were good.
Great Product but wire length needs to be shortened 
2008-06-28
This product works fine, but when I tag it along with my JVC headphone, the combined wire length becomes unmanageable.
Great companion 2008-06-16
This is a great companion to my JVC noise cancelling headphones. I don't really need the extra length while traveling, but at home the added range and direct volume control is a big plus.
Does not turn sound up; only turns sound down 2008-05-31
I have discovered, as have others, that most modern TVs do not have a simple output jack for headphones. Instead they have a limited volume output set of jacks. The sound coming out of them is set pretty low and you cannot increase it using your remote's volume controls (I guess the manufacturers figure you are going to hook it up to an amp and a theatre sound system, which is not what I wanted to do.) So I heard about this product and it seemed like just the thing I needed to boost volume. Wrong. It has no power source, so if you set the dial on the unit at maximum volume, it comes to your headphones at exactly the same weak strength as emanates from the TV output jacks. All it can do in reality is turn the sound down. Skip it.
