General comment on tests performed

The magnetic field results are very interesting but no mention of the frequency range examined is included in the extract. As an EMC engineer problems are often encountered above 30 MHz, and more particularly when external devices such as earbud headphones are connected to high speed devices. The earphones act as very effective antennas.

Nothing against Ipods but I don't know their EMI footprint with headphones connected- I'll check the EMC declaration in my Ipod.
