Etymotic Etycom headset

Tried it out in the noisy environment at the Moscone center, and the
sound quality was just stunning. Even though it was horribly loud all
around me, during a telephone conversation with the Etymotic Etycom
headset on my Treo, I could here the other party exceptionally clear,
and the caller told me, that he understands me perfectly, even though I
was just talking with a low voice in this noisy environment. From now
on, this will be my preferred telephone headset.
