The gel inserts on the Jabra is quite uncomfortable, at least for me. It's a bit hard to make the earbud stay in my ear, and forget about jogging wearing this. Also the insert comes off very easily, and if a friend wants to borrow it and has different size of ears, you need to find the other sizes of the insert. Sound quality is mediocre, as callees often complain about wind noise from my end. I'm not happy with these.
