1) Frequency response is meaningless unless you show the response curve. The rolloff at the low and high ends is probably so much that there is essentially no low or high frequency response;

2) CDs andf other program sources have essentially no output at the low and high frequency ends so that if the headphones really did have any sort of response at these limits, the program sources do not have any output there;

3) The human ear does not have any ability to hear a 22,000 Hz tone and very limited ability (if any) to hear an 18 Hz tone so, again, response at this range is useless. Most young people have caused enough damage to their ears that they have reduced hearing ability and older people have high end hearing loss as a natural part of aging.

Bottom line – these earphones may sound good but the specs are useless lies.

Thanks for the tip on altec-lansing. I’ll try to get a pair to try out.

I will say though, the Apple Stores carry a decent pair of altec-lansing headphones called "airphones" which are designed for athletes who need to be able to hear while running, biking, etc. Not only are they great for athletics, if you use your headphones as a handsfree, it's safe to drive with them because you're not blocking outside noises. </p> These look nice!
