Does it connect directly to the lecture website to download them, or is it just an application to put the MP3s into iTunes? (cause it would be much easier to download the lecture MP3s and put them into iTunes yourself...)
I just got the Etymotic earbuds, and they work AWESOME! The 650 basically has open pipes, and the earbuds work well enough that I can easily understand a book on tape at 70mph, even at a volume level that is comparable to conversational speech (i.e. not blaring and destroying my ear drums). It was a tossup between the Shures and the Etymotics, though... I'm interested to know how the Shure earbuds fare.
