UK'er who loves Omega's enough to mention it in a letter to Adam Savage??? Plus bonus airplane history and machining talk.
He mentions Phonak haring aids - I had some Phonak audio earbuds a decade ago that were pretty good sounding. But I stayed with Westone Audio earbuds since 2007 (they also make hearing aids). I have 9 different models of universal fit Westone, from the W1 through W80, and three different custom molded models (ES3X, ES5, ES60). Someday I'll have Westone hearing aids, LOL. Adam's had that Omega 3313 powered Planet Ocean for at least a decade, or more.
