 lightweight, good sound, & keep a lot of ambient noise out November 25, 2008
I've used these for quite a few years now, but the one thing that always bothered me was that one plug always went dead after a few months, and I'd have to get a new set. Granted, I used them when working out among other things, so I gave them a beating, but it was still annoying. I then bought a much more expensive brand, based on reviews I read here at Amazon. And I have to say, those others REALLY annoyed me. They're too heavy and didn't fit into my ears as well. And because the wire's heavier, they're more cumbersome. Also the sound was supposed to be so superior, but I found very little in the lower frequencies. So I'm back to these. And I have to say, the ones I've gotten recently don't seem to break as quickly. Maybe I'm being more careful, or maybe they're making them better, but for the 12 bucks or so that I spend, they're definitely worth it.
A great price until checkout November 17, 2008

Graet headset 2nd time I purchased the "Sparkplug". Nice sound and isolation for the money. To me they sound as good or better than the $30.00 sony phones they replaced. The shipping time was really fast, US mail as I recall. I just wish these companies would all disclose S&H costs before the end of checkout. A padded envelope could have been sent for "3 postage stamps "tops". I understand they need to pay someone for the boxing and so on but I don't like to be baited by the lowest price on the web, only to find high ball S&H charges. Were not stupid were going to see the total!!!! You prices and service are as good or better as anyone elses in the subtotal category This appears to be a good company, they should refrain from those practices
 Good solid product November 7, 2008
Did my research, bought in quantity. Have gone thru about 3 pair in last 2 years, which is a pretty good lifespan for such an inexpensive product that I use for at least two hours every day as a runner. They stay securely in my ears, canceling some noise, offering pretty good sound quality. Much better than the original iPod set.
Only vulnerability is where the wire connects to the plug. Lots of repetitive jostling over time results in cracking of the thin wire. I've addressed the problem by simply wrapping some tape around that vulnerable point, which keeps the wire straight and unstressed.
I recommend it.
 Muffled Sound Ruins Good Design November 3, 2008
Everyone has their preferences in phones and their dislikes.
I ordered these when I ordered the KEB-24s, thinking I'd like these more. These fit better but to my ears, they are muffled. I like the others better.
The best low cost earbuds October 22, 2008
These are the most comfortable earbuds I've ever used. The form fitting foam inserts are the best on the market and the frequency response is exemplary. Great bass and exceptional hights. For the price, there isn't a better set of personal earphones and even when price is considered, they rank near the top
Koss pioneered headphones way back when and they continue to be the standard for this type of device
