Query: Medium quality for high price product

I bought an iPOD (8GB) and I thought to upgrade my listenning experience by buying extra high price earphone from a very good company (altec lancing are great in speakers).When I plugged them into the iPOD i was supprise by the sound image mediocracy.The original iPOD earphone are much better.So, I thought maybe impedance do not much the iPOD. So I test on my Denon Hi-Fi, Still iPOD earphone had much reacher sound.Most of the time I never regret buying in high price. This time, I don't know what to do with these earpohone.I can say that sound seemed to be accurate, but lack of Bass, treble is not smooth (I wouldn't pay $20 for these earphone).Joel
