After waiting since CES for the SPH10H to be released, I finally managed to get one, only to find that it doesn't fit in the V of my helmet straps. On all three of my helmets! Fortunately, it looks like the SMH10 with earbud baseplate will suit my needs better anyway. But, it does beg the question, which helmets were tested and are compatible with this beast? Sena needs to publish a compatibility list, or get ready for a lot of returns. It was a clever idea, in concept, but in actual implementation, it didn't work out so hot.
sph10h Helmet Compatibility List?
