Summary: Poor design due to minitiature volume control wheel. You have to use fingernail to turn volume wheel! Didn' t ANYONE even try out this poorly engineered device? I returned it and spliced an old pair of earbuds instead. sorry Koss, you blew it!!!
Summary: Great for reducing your volume if it's too loud. It has a clip on the wheel end which is nice. One con though, the box on the wheel end is made of plastic and doesn't feel very sturdy (I would definitely not drop it). Overall works fine but I would watch the one end.
Summary: I use this for my metal detector, the detector has no external volume control, the heat of the sun makes the headphones hot, so with the 1/4--1/8th inch jack reducer and jvc water resistant earbuds this works great...
Summary: I bought this item to use with my mp3 player when I'm working in my yard. It is real convenient to just reach up and turn the volume up or down without having to dig my mp3 out of my pocket each time; especially when I'm on my lawn tractor. The clip holds firmly on my shirt pocket.
Summary: Very disappointed with this volume controller. I attached it to a new Koss headset which had no sound control & discovered that the volume controller was throttling back the sound from my iPod . I am hard of hearing & need the sound a bit louder than most...I could barely hear any of the music with this controller attached. I bought this controller so I could adjust the sound using the in line controller instead of constantly using the controls on the iPod.
