Koss 155954 VC20 Volume Control, Standard Packaging, 39-Inch Cord, Compatible with Cell Phones and Headphones

I listen to old radio shows to fall asleep to, and the volume levels can fluctuate quite a bit. I had this in my wish list for years but for some reason never got around to ordering it. Well I finally did and very happy with this control. The cord is only about 39 inches, but that's OK for my use. Cord is soft and pliable feels like it should last quite awhile. Turning the volume dial creates no clicks, static, etc. Perfectly silent as it should be. What you would expect from Koss. Great company. Wish I still had my old Pro 4 AA headphones. Now it turns out I;m sorry. Sorry I waited so long to get this volume control, it works great. And for those who need it---No it will not make your device louder, but it will let you control the volume you have, and do it right 0-100%

I already have two "no name" inline volume controls, but I needed another. This Koss unit was no more expensive from Amazon than another "no name" from an electronics store, and I've been a big fan of Koss since the late 70s, so I bought it. First, what it IS and ISN'T. This is a volume control, but NOT an amplifier. It will make your MP3 player, etc., quieter, but NOT louder. If your source is too quiet, look for a headphone amplifier. When I used to listen to a cassette walkman it was easy to turn down the volume when I needed to. The volume control was a thumbwheel right on the player. I have several MP3 players now, and they all have hi-tech context sensitive controls. This means (for me, anyway) that I have to look at the screen to make sure the button or slide control is set for volume. This control solves that problem. Set the player for a volume slightly on the loud side and use the inline control to get comfortable sound. If you need to lower the volume (to talk to someone, for instance) you can use the volume control without taking your player out of your pocket. This model has a three foot cord between the player and the volume control. This is nice if your player has an FM tuner -- MP3 players use the headphone cord as an FM antenna. My generic ones were only about 8 inches long and the FM reception suffered. The control has a clip on it, so you can wear your player safely in a padded pouch on your belt and clip the volume control to your chest pocket. A few reviewers have noted that lowering the volume attenuates high frequencies. I tried using the EQ settings on my player (I was also using Koss PortaPro headphones). When I had Bass Boost EQ settings I did notice some high frequency attenuation in both the Koss and generic inline volume controls; when the EQ was turned off I didn't notice as much high frequency attenuation, but the sound was very "flat." Anyway, I don't think I would have noticed it if other reviewers hadn't pointed it out. An inline volume control is very handy for portable MP3 players, etc., and this unit is well thought out, and works great.

If you're looking for an in-line amplifier with volume control, this isn't it. The Koss VC20 provides low-impedance volume control where it may not otherwise exist. It works with standard 3.5mm "mini stereo" headphone jacks. You can also use it for other clever things such as individual line volume adjustments without the use of a mixing board or compressor. Koss makes good stuff so, for what it is, it works great. The gauge of the cable is rather thin and it feels flimsy but, otherwise, it works great. I hope to see them re-release handy gadgets like the three and five-band equalizer/amplifier boxes that run on AA batteries.. I tried to look for that and no one seems to have them anymore. In short, keep in mind that this will not exceed the peak volume level of whatever devices you chain it to. I did not notice quality or maximum volume loss so that is a HUGE plus!

High-quality volume control - Smooth volume resolution from quiet to loud. I bought an off-brand before this and it had no low-volume resolution at all. That one went from quiet to loud almost immediately, and from there ramped up to full volume. These Koss ones work beautifully. My lesson learned - stick with a true audio company.

I bought this when my Skullcandy earbuds with their in-line volume control died of broken wires and I had to resort to using the earbuds that came with my iPod (horrid things). I use them at work and need a way to turn them down quickly if I need to hear something. This volume control far exceeds my expectations, especially considering the price. It performs much better in terms of range and resolution of control than the built-in one. The packaging claims it "increases volume", but I have yet to verify that and don't see how it's possible without some form of power. The extra cording and clip are great extras, too. I usually tuck all the extra wires into my shirt to keep them out of my way while working, and was constantly losing the built-in control inside my shirt. This one clips onto the shirt front or pocket (still figuring out where it's best located) so it's always easy to reach. Only two issues to report - the springiness of the clip and the company's customer service. There isn't much of either. The clip is easy to bend. So long as you clip it to similar thicknesses of materials, it's fine, but if clipped to something thick such as a jeans pocket the clip will be sprung open enough that it will not clip to a thinner fabric later. A pair of needle-nosed pliers will put it back into position for thin fabric pretty easily, but I don't believe should be necessary. There are better metals more suited to that type of duty and the clip should be made of one of them instead of what it is now. I don't know how Koss' customer service will respond if there is a problem, but I first e-mailed them about how pleased I was on the VC-20's performance, and then again later about the clip issue (not complaining, just letting them know). That was several weeks ago and I have yet to receive any response on either, not even an automated "we got your e-mail and someone will respond shortly". Their website had great testimonials on their high level of service and customer satisfaction, but I haven't seen anything to prove it. Overall this is a wonderful volume control. I am very pleased with it, would buy another, and recommend it to anyone wanting an in-line volume control. In fact, I have dropped "in-line volume control" from the spec list of my next set of listening devices.

I bought this because giving Tidal exclusive control of my little soundblaster play 3 locks the volume at max (real fun experience finding that out), so I had get either a little volume control like this or just go all in and buy a DAC. Given the times, I decided to get the former and narrowed it down to this or the volbox and, well, lemme just say I'm not going to spend $20 on what's essentially just a potentiometer and a knob when I could upgrade to a proper budget DAC/amp for just over double that. Anyways, onto the product at hand. I figured the Koss VC20 was it: low price, Koss' reputation for fantastic value, and a simple solution. Package comes in, I received the same red-labeled new model that recent reviewers have been getting. My iems go in one end of the VC20, the other end goes into my sound card, turn the volume to about half, I queue up a Master quality track on Tidal... It's fantastic... for all of 10 seconds. The audio quality started degrading very, very quickly. I tried the ol' unplug and plug back in to see if that was the problem and that gave me another few seconds before the song faded into static-y distortion. "This isn't right", I say, plugging the volume control into my phone to see if it's happening there too and, you guessed it, same soup, just reheated. After a bit more fiddling I found out that the plug wouldn't sit right in the port unless I constantly applied as much force as I could to constantly keep the plug shoved in, otherwise it would start slipping out of alignment and ruining the signal. Instant return. Immensely disappointed with Koss for this product. Guess I'm just going to bite the bullet and pick up the DAC I was eyeing.

One of the first things I do when I'm buying new ear buds is check the cord length. The majority of ear buds these days have cords that are much too short for everyday use often resulting in the ear buds pulling out of your ears or the cord coming unplugged from whatever device you're using. This is where an extension cord/device such as this one is very useful. Like many people, I sit at a desk in front of a computer all day, listening to music much of that time. The iPod dock that I have on desk is just far enough away that my ear buds don't quite reach and wearing them isn't practical or comfortable. Thus I purchased this item to add some cord length and some extra volume control. Here are my thoughts; Pros + Adds approximately 3' in cord length. + Volume control switch is at the end of the cord and has a clip to attach to whatever you're wearing or carrying. Cons - Sound degradation is extremely noticeable. Feels approximately like a 30-40% loss of sound because of the extended connection. While I expected some loss I didn't expect quite this much. The Volume switch barely raises the overall volume unless you have your device volume at max. - Flimsy wiring and weak connections tend to short out quickly if there is moderate or active use. - Amazon's stock photo doesn't exactly match the item I received. My model matches the customer image that was submitted so there are slight differences such as the angle of the male end of the plug. Could be problematic for some. While this item is useful to me in my particular situation I'd rate it poor overall. It works for me because it will stay at work on my desk and not see any travel use. Since I don't listen to my music very loud at work as I need to hear if coworkers are speaking to me, the low volume isn't a huge issue for me. However, if you're looking to purchase an extension for your normal headphones to carry with you this is NOT the device for you. Especially if you're going to be around a lot of noise or people talking (i.e. the bus, train, subway etc.). If you're going to be in any of those situations you're better off going with a different product.

全てにおいて、私のアンテナが受信w 音質、音圧、高音、低音のキレ言う事なし。ノイキャンはダイヤル、アナログ感むき出しのデザイン、機能いゃ〜購入してよかったです！

Un producto simple que funciona de manera adecuada y con calidad buena acorde al precio.

If you are looking for a compact inline volume control as an extension, for either earbuds or headphones when it may not be easy for you to control the device directly, I would highly recommend this.

Purchased this so I could control the volume of my PC speakers which I am using for my Xbox, this cable allows me to adjust the volume as the controls on my actual speakers are only compatible with Windows
