ECCI is introducing a new line of IEM call the PG series, aiming at the bottom end of the market. The first in the series, the PG100 is actually less than US$15, uses a more generic all plastic housing and meant to be easy to drive at 18 ohm impedance / 104 dB sensitivity. I am quite impressed by the latest of their PR series, the PR401, so the natural question is - do they really need to go to such an low end of the market?
