Driver size does matter!

You get what you pay for usually.
Well I'm thoroughly impressed.
Everything is first class.
Looks don't make sound, but in this case looks just enhance the best ear buds I have ever heard. Really!

I thought I would give these a try, so I purchased at the Sony Style store with 30 day money back like Radio Shack.

I have a Palm TX which has an MP3 player built-in. I'm new to MP3 but been a audiophile for a long time. Cheap head phones sounded much better than cheap ear buds but (a requirement) don't block out enough ambient noise on the "BUS". I don't want closed or noise cancelling headphones. Sealed, in the ear canal, ear buds are more comfortable, but do they have any BASS? You bet they do.

Take a look at these specs. They are superior - 5 stars!
* 13.5mm driver for wide frequency response(most are 9m)
* Neodymium magnets (rare earth) Gold plug - matters!
* Metal Housing to eliminate vibration
* Hard leather carrying case - real leather
* 3 size ear buds
Audio:
Sensitivity --- 106dB/mW
Impedance --- 16 ohms
Frequency Response --- 5Hz - 25,000Hz !!! for real

These babies thump the bass, and w/ crystal clear highs.
Sony does make excellent equipment. I've had several Sony portable shortwave radios, component stereos, and never been disappointed. Buy these buds, you Vill love them
