Customer Reviews

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.
