I know this has been talked about before, but with gear changing so quickly, I was thinkin I'd drag it out again.
I picked up an 8 gig Sansa on Woot the other day for $30 shipped. Rather than blow out the entire lake, much less those in our own boat, with tunes that they may or may not care to hear, I thought I'd check out putting an MP3 player & headphones on myself as I ride. Let those in the boat listen to whatever they want, I'll listen to what I want.
The Sansa is tiny (like 1" x 1.5" x .5") & there are plenty of waterproof armbands, bags & housings for it that I can easily put it on my arm or on the shoulder of my vest comfortably. Even vests with pockets in them now days.
Now I'm looking for headphones. I always wear a Protec helmet so I'm thinkin I'll just wire up the helmet with a descent set of waterproof earphones. I checked out H2OAudio's, but they are getting lousy reviews saying their not durable. I even checked out the new ShreadReady helmets with the integrated headphones but didn't like how it fit on my noggin (yea, yea, let the jokes begin).
I'm lookin thru Ebay now. Anyone have any suggestions?
