Craig at Get Plugged is a real pro at making these ear-plugs, I highly recommend him...
I got the bluetooth model, the plugs work great but I wouldn't rave about the bluetooth technology, It works fine for one channel at a time after some fiddling but won't pickup other channels eg;
While playing itunes, my gps won't speak to me or my cellphone, It's either one or the other & I need to reconfigure each one in settings...I tired quickly having to constantly pair all my devices to the bluetooth earplugs...On the other hand,
My old Jabra bluetooth earbuds would pickup all 3 of my channels eg;
While itunes is playing a gps voice command would interrupt the music momentarily then go back to tunes etc, The trouble with the Jabra's was I needed a shoehorn to fit the helmet past my ears, plus I had all the wind & road noise over 60kph, So I'm now mainly just using my bluetooth earplugs as ordinary earplugs...
