I have tried every conceivable type of headphones costing less than $20 around: the Sony stick-in-your-ear style, the original Walkman style, the ear bud style, the Panasonic clip-to-the-ear, etc. There is something wrong with the sound quality for each of those types.
These headphones only cost a little more, but the quality is much better. I believe that this is due to two factors: the neodymium magnets, resulting in better bass and treble, and the behind-the-head style which keeps the speakers closer to your ears, allowing you to hear all the sound.
There is one disadvantage to these headphones for me: I wear glasses, and the headphones pinch my ears against the eyeglass frames. To get around this I just sit the eyeglass earpieces on top of the speakers.
I'm not associated in any way with EarHugger, Amazon, or anybody else that has anything to do with these headphones. I'm just an ordinary customer.
