Editor: Thank you to Michael Fremer and John Atkinson for taking the time to review the Perreaux R200i in June 2003. It is refreshing to feel that the unit has been subjected to a reasonable level of scrutiny by your publication, and as such it is proper that our company be given the opportunity to respond:

Regarding the channel naming, to ease confusion in future, we will consider changing the rear-panel transfer. In the interim, we will consider changes to the product manual.

The Twin Mk.III was of slightly above-average sensitivity, at an estimated 88dB(B)/2.83V/m. The impedance (fig.1) stayed above 6 ohms almost all the time, with a minimum value of 4.5 ohms at 190Hz. The speaker will therefore work well with modestly specified amplifiers. There is a significant glitch in both the magnitude and phase traces around 250Hz and a smaller one at 700Hz, which implies the existence of cabinet resonances of some kind. Investigating the enclosure's vibrational behavior with an accelerometer didn't reveal anything untoward at those frequencies…

Laugh if you will at my priorities, but I'm much likelier to leave on a trip without my suitcase or my tickets than without a pair of Etymotic's unique "headphones." After all, what's more important: clean underwear or good music? Okay, okay—I'd rather have both, but what's personal hygiene compared to musical ecstasy?

The ER-4, in fact, is an extension of the design of the Tubephone insert earphone, designed for audiometric research. This device—which placed the transducers in a pack that connected to the ear canal via a 12" hollow tube—…
