Used this to control volume through headphones from a TV (with a converter box that does not have internal volume control)Works as described - sound quality is good.

The volume control works as described and is well made.

The Koss VC20 Volume Control works very well with the Audio-Technica ATH-ANC7 QuietPoint Active Noise-Cancelling Headphones

Works well, but to many issues working consistently with my wired headsets.

A true audiophile might have some issue with it, but for general use, this works like a charm.

And when you need a volume control (down only) in a 3.5mm format, this one works fine.

I recommend this if you want a nice simple volume control that works.

worked as expected, no complaints.

works as expected, good product! extends your wire ,gives you more space from your player to your device

Worked as expected, at $8, I thought it was a little overpriced.

They work just as expected with no degradation to the sound quality.

The product works as advertised, and is very simple to use

Works as advertised and is a pretty hard to find little item these days.

Works as advertised, great mini-amplifier for headphones.

I'm taking off one star for false advertising.

This way we can both have it as loud or as low as we want.

Despite that,this is a good control & it doesn't have a stupid price.

The price is right and this extension can be used with any headset

Good price and does exactly what it was intended to do.

THe price was right and the thing works as I expected it to

volume wheel is a bit small, but other than that great price and it works.

Plug into your koss headphones and get easy volume control

Works great as a volume control on headphones plugged into a HDTV

This item would probably last much longer than the cheap Radio Shack control, but the sound quality is completely unacceptable

I recommend this if you want a nice simple volume control that works.

(most cheap volume controls (potentiometers), start making noise after a short while).

Its a little embarrassing using this ugly thing when I really like the look and feel of my headphones.

You don't use buttons; on this unit you use a dial (which to me it is a good thing).The cable on this unit is pretty long, so I imagine it can also be used as an extender

The MS Zune ipod is a great little thing but just doesnt have the volume needed to watch some low volume videos

Admittedly, it doesn't say that on the Amazon page, so that's a good thing

You can also use it for other clever things such as individual line volume adjustments without the use of a mixing board or compressor

This item works well with the headphones I purchased and gives them a little jump in volume that makes listening to audio interviews that much easier.

If you just want to be able to control your volume with a wheel, then this is a great item, but it wasn't what I was looking for.

An extremely useful item for laptops that don't have a manual volume control

Perhaps this item should fall into the category of you get what you pay for

Unfortunately the item and its cord is very bulky and introduces static every time you bump it

I'm sure there's some quality loss introduced by putting this device between the source and the headphones, but I'm unable to discern a difference

This little Koss volume control is a cheap and effective device.

Device works and is very helpful if you need a volume control for headphones.

It works well with TV sound out either directly or thru another device like a blu Ray or amp

This device lasted until two days past the Amazon window for returning items, then crapped out

Unfortunatly, after just two hours of use, the sound became distorted and i could not understand the conversation in the movie

So if the device has a poor sound and volume range, this does nothing to improve it

The sound quality of the Koss R-80, with the 16Hz-22kHz range, which to me is an important factor, allows excellent sound reproduction and no issues.

Sound was fine until then, now its a constant struggle to get the plug situated so that there is no static.

i connect an altec lansing orbit speaker to airport express, but there was no way to limit the volume, coz when the sound transmission starts for the first time the sound was very loud and could damage the speakers

Agreed, it was inexpensive, but I still have a volume problem almost as bad as before I got it.

A very inexpensive way to save your hearing on a treadmill with cheap volume controllers that won't let you get the right volume setting--either too soft or so loud it was ruining my hearing

I would recommend it to someone looking for an expensive way to increase volume slightly

I use this to attenuate way-too-loud signals for my in-ear headphones, and an accidental volume increase can be very unpleasant!

Overall it works and gives me a way to control the volume but not as sensitive as I would like.

The volume control works well and I am pleased with this product.

A volume control that I can reach anytime, and it works

For that, even the lowest volume setting on my phone is just too loud

but the TV volume control is inactivated while the box is plugged in and the volume was LOUD with no way to control it.

Without the Koss VC20, the volume from the headphones is way too loud

Works fine for now, Iĺl tell you later how much it lasts

I have a hearing problem and always need the TV on loud

My husband who has intermitten hearing problems can use the volume as high as he likes while I can keep the TV turned to a normal level.

Needed a way to listen to television when one of us has a hearing problem

Agreed, it was inexpensive, but I still have a volume problem almost as bad as before I got it.

I bought a set of noise cancelling headphones for a trip and want to use these to control the volume

and it actually made the headphones sound worse than when I did not have this volume control in

I purchased the Koss VC20 "Remote Volume Control" when I bought my Audio-Technica ATH-ANC7B noise-cancelling headphones.

Overall it works and gives me a way to control the volume but not as sensitive as I would like.

Works great, I was using headphones for my TV's stereo output and the sound was way too

I hooked the Koss volume control between my computer and speaker and speakers are great with no extraneous noise.

Works beautifully; no noise and the volume is sufficient

Works beautifully; no noise and the volume is sufficient

The volume control is smooth and noise-free, smoothly adjusting the volume from zero to full with one rotation of the compact dial inset into the mechanism.

I have nice noise-cancelling headphones that I use with this item and can not tell any audio distortion or loss of quality by having them plugged into this as opposed to being plugged straight into the speaker.

Works well for a split connection where you don't want to limit the volume on the other feed.

After enough cycles, all built-in sockets begin to make unreliable connections and eventually fail.

I've occasionally noticed that the connection isn't perfect, but mine's been banged around a lot and dragged on the floor of my study.

I bought this with a specific use in mind: to use it with an old but good n' comfy Sony MDR-A34 vertical in-ear short cord headphones and my trusted Sandisk Sansa Clip Zip playing flac files

And you know, adding more audio plugs and sockets threatens to make more scratchy connections
