The unit works, and it's about the only type of volume control available that's small and portable.Sadly the Amazon listing is outdated, the newer upgraded unit isn't even shown on the Koss site. Updated unit does not have clip, and only has 90 day warranty instead of "lifetime" warranty which Koss doesn't honor anyway (requires you to pay shipping/replacement cost, will cost more than buying new unit!)

As other reviewers have stated, the quality of this is such that it doesn't last long. I've had at least 3 of these, and while the first one lasted more than a year, the last 2 have only lasted a few months each. Eventually, it gets to a point where the connection with the source device is not steady, and sound cuts out from one channel unless you readjust the connection.
Other than this, I like the form factor. In fact, I can't really find anything else that I like in this regard. The volume adjustment itself is fine. While some may say the range from lowest to highest volume is a short turn of the knob, I don't have an issue with the "throw" of the knob. It's also a good length for me, since I'm usually using it with my laptop where it's not convenient to adjust volume as needed.
Currently looking at headphone amplifiers as a replacement. If I'm going to be buying 2 or 3 of these each year, I might as well spent an equivalent amount and get something that will last a few years or more. At the moment, the Proster Headphone Amplifier (https://smile.amazon.com/Proster-Headphone-Amplifier-Rechargeble-Computers/dp/B07D9HPDWH) looks like the best option in terms of price, size, and convenience.

I have previously owned two (2) of these KOSS small amplifier units. At the time believing that the KOSS brand name would guarantee excellent performance and long life. I was wrong and even by giving a 'second unit purchase' the benefit of doubt!
Both units worked well for just over a month and then the connection started going out and only giving distorted sound through one ear-bud! Further the volume adjustment created humming and constant static in the line. At first I physically held and pushed the connection in tighter but knowing that the time of life of the unit is about to expire. I have purchased many Koss products in the past 10-years and then several expensive Studio amd Pro headphones. And this is the third time I experienced trouble and a generally cheap product offering.
I realize that this is a very small KOSS amplifier unit and certainly a low-cost item, but at the same time that is no excuse to abandon or drop the quality from the previously high quality perceived KOSS brand.

Cheaply built. Worked great for just over a month and then the connection started going out.
Reviewed in the United States on March 9, 2017Product Packaging: Standard PackagingVerified Purchase
Cheaply built. Worked great for just over a month and then the connection started going out. When it arrived, nice clear stereo sound through both earbuds and the volume adjustment helped me turn my music down low enough. Now, the connection is going out between my headphones and the volume control unit so I only get sound out of one earbud unless I physically hold the connection in tighter. When I turn the plug, the sound evens switches from one earbud to the other. I guess this is just another cheap knockoff from China that is starting to proliferate Amazon.

What a hunk of junk. Don’t waste your money on this product. For starters I can only turn the volume control a centimeter either way for almost unaudible minimum volume to very loud max volume. Second, I have to fight with the wire connection in order to get stereo play back. Otherwise all I hear is the right speaker. Would be a law and somone held accountable for peddling such garbage. If this rating system provided a zero star rating I would definitely give it one.

I'm replacing another cheaper volume control adapter with this one. Right out of the box I can tell this one is made much better. I bought the $6 round shaped adapter previously (the round one you probably just looked at, or see in the related products right now). That one was no good. As you adjust the volume the level in each ear slightly changes and you have to fiddle with it so the volume is even. Very frustrating.
This one raises the volume nice and even, and the cable is pretty long so you get a good extension out of it too (which might be a bad thing if you are taking this on a walk and don't want the extra length).
I'm glad they put the volume adjustment at the end of the cable instead of in the middle like that other one. I think that was the biggest issue as it put all tension on both sides of the volume knob which is probably why it wore out in a matter of weeks. I'm not sure how long this one will last yet, but I'm sure it will last much longer!

A Great Volume Control, But Be Aware of Stereo Mismatch
Reviewed in Canada on August 1, 2019Product Packaging: Standard PackagingVerified Purchase
For those of you looking for an inline volume control, this is the unit I would recommend. Koss is a very good name (I've seen their products used in supermarkets and other commercial applications) and I have never once had any issues with them or their products. The only reason I didn't give it five stars is because sometimes the left and right channels don't perfectly match in terms of their individual volume levels, although this isn't too surprising given the inherent imperfections in physical potentiometers (especially the multi-gang designs). So overall, I would say be aware of this potential issue (it can be fixed by gently rotating the control knob) and you won't have any problems at all. A well-designed unit that will impress every audiophile out there.

Cable de extension de audio 3.5mm con control de disminucion de volumen
Reviewed in Mexico on June 16, 2017Product Packaging: Standard PackagingVerified Purchase
La calidad del cable es media, cable delgado. No es a prueba de enredos.
El control de disminución de volumen tiene una pequeña rueda tipo perilla para controlar el volumen. El control en si no es muy robusto así que hay que tratarlo con cuidado.
Yo lo uso para conectar unos audífonos a una señal de audio convertida de digital a análoga que sale se una TV Samsung y pasa por un DAC. Con él controlo el volumen hacia abajo del nivel de referencia que proporciona el convertidor.
OJO: Esto no amplifica la señal (o sea que no sube el volumen).

I use a radio, a Sony ICF-7600GR, that is a little "hot" on the audio output jack. Even with radio volume at minimum the sound level was too loud for my mono earphone. I listen to AM radio stations overnight with that earphone, so it was critical to reduce the volume to a level that was still audible, but not distractingly loud.
This unit arrived today and I tested it immediately. It works perfectly, and I now have much more control over the volume level. I presumed it would work OK with mono, even though it is made for stereo - and it works great.
Very happy with this purchase. Koss is a quality brand. It's maybe a lot of money for a simple potentiometer - but the build quality made it worthwhile.
