................... Again, if you have an IE800, do you hear a big drop in level (13 to 15 dBSPL) as the sweep transitions from 1 kHz to 3 kHz? Some may, but I think most will not. Again, I definitely do not.
No drop at all on my end from 1k to 3k but there appeared to be increased energy at around 5k and 7k, which I believe was Sennheiser's goal in preserving detail when competing with external ambient noise.[/QUOTE]
