New Spark Plug need tempering (to make its quality improved and stabilized). After that it is perfect for its price to enjoy Rock music or Pop music.

I have tried many different types of ear buds and none were as comfortable as these. Good quality sound at an affordable price.

These are good while they last (which is not very long) around 2-3 months. I've had about 4 of these because I don't want to be carrying them around, but always want to have them handy. The cable quality is extremely bad in all the ones I've owned. They have not been abused since I don't carry them around and if I compare them to the the ones I use with my nokia cell phone which are really abused you can tell the difference, the cable for these feels really thin.

I bought two pairs of Sparkplugs a few years ago and was hugely satisfied with them, especially the sound quality: deepest, richest bass I'd heard from a tiny earpiece. THESE ARE NOT THE SAME! While what I purchased looks just like the old product, the sound quality is completely gone, now just as tinny and thin as all the other in-ear speakers I've tried. If you want even modestly decent sound quality, look elsewhere!

Don't waste your money. Buy 2 pairs of Koss KSC75's or a pair of J-bud's. The sparkplugs sound terrible.....all muffled bass.

Maybe my ear holes are smaller than everybody elses. These things fall out of my ear when I smile, or when I frown, and I get a complete upper body workout when I walk with them on...first it's one falling out, then the other. They would be best used with super glue. I really don't understtand ear buds, give me headphones with the over-the-head band anytime.
