What our customer's say!

"A great price until checkout", 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", 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", 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", 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

"Great cheap ear buds!", Great sound quality for such a low price.

My favorite part is the squishy foam on the ear bud. You squish it and let it expand in your ear. This is great not only for blocking out some of the outside noise, but it keeps them in place.

I have no problems with these coming out when I exercise. They stay in even when you are upside down.

"Good purchase for the money", I have been using these ear plugs for over two years now. Usually they are in the front pocket of my backpack ready to go. The price is cheap enough that I don't have to be careful porting them around. Made like an earplug but with a hollowed out center, they are good at minimizing noise around without having the more expensive noise canceling devices. Personally I like booming bass and these little plugs deliver. The one thing I would do differently is ship it with a carrying case as the long wires can become tangled.

"Comfortable and Bassy", I think these headphones work great for running. Simply squeeze the foam and place it in your ear. It expands enough to stay put. It does a great job of blocking out outside noise, almost to a point of danger especially if you are running on roads with these. You will never hear a car coming.

They do produce a lot of low and tight base. The treble is above average.

"Sleep well!", Is a very good ear phone. Sometimes I sleep listen music using the Koss Sparkplug and sleep with music is a good thing to do...

"Variable quality?", While others have found these buds to be pretty good, my set is horrid. They have underdamped bass, overbearing "boxy" mids and dull high end. The tape mod helps a little but not enough to make them listenable. I suspect that there's a lot of variation from one set to another -- they're cheap, so cutting corners on quality control wouldn't be a surprise. For the price they're worth a gamble but be forewarned. I've had much better luck with the Koss Plug (not "spark"plug) units.

"Sparkplugs", This is my second pair and they are great. I use them on a motorcycle and they really block out the wind and exhaust noise because they go right into your ear canal. They have great range of sound and for the money you can't beat them!.
