Jabra Stone 2

Pros: incoming and outgoing quality is great; device is very light; great design and form factor.

Cons: Very uncomfortable fit; won't stay in my ear canal, keeps poping out. Very frustrating to have to keep adjusting it back in the ear canal

Summary: I have been using this for four months. The only negative for me is the fact that it does not fit my ear canal. I love the design and features, but now I avoid using it because it keeps falling out of my ear canal.
