For anybody wanting the battery version of the Jabras, the 20’s are much wider than the 10s (to accommodate the telecoil and larger battery I think). I’ve been using for a few weeks and still having trouble getting used to the size. I don’t know exactly why they bother me, but they do. I’d love to have the latest tech (although the LE audio is a disaster with my Galaxy Flip 5), but I’m considering sticking with the 10s for the size.
I don’t hear any huge difference in the audio quality between the two. Only thing I notice that is better on the 20s is the range of the bluetooth connection. And of course the battery life is longer due to the larger battery, but the 10s last 4 or 5 days which is fine with me.
