Thought I'd post a quick comparison on the two after being able to use both. I first had the Bose then just started using the Jabra this week because the Bose doesn't fit perfectly to my ear.
Sound:
Very similar sound profile. Bose probably has a tad more bass but overall very similar really. I'm not a audiophile so take my opinion on this with a grain of salt.
Fit:
This one is very personal, one might work for you better than the other. The Bose for me doesn't fit properly. I've tried to small and medium ear tips. Small just falls right off, where the medium fits but starts to hurt after 30-45mins of use. The Jabra ear tips fits me much better and I am able to wear this for hours with no problem.
Controls:
I never really used the buttons on the Bose since it's a bit too stiff to press. By the time I'm able to press something, it would've fallen off from the pressure. The Jabra's have a nicer control feel and setup. Forward/reverse and volume controls are easy to use.
Usability:
The Jabra has this niggle where if you pull out the left ear while playing music, that side will stop but the right ear continues. If you pull the right ear, both stops completely. For what genius reason was this done for? The Bose will keep playing on both sides no matter which one you take off, which means you can share one side to another person in case you're showing a video or wanting to share music.
Design:
A lot of people always talk about the Bose making you look like you have Shrek ears. But personally wasn't too bad for me. The Jabra is smaller and more discreet in the ear so if that's important to you, then this one is a clearer winner.
Battery:
Bose will always be better in this department. During use, it will last about 1 hour more than the Jabra. The Bose case also holds more charge than the Jabra so overall the Bose will last longer. The Jabra case is half the size of the Bose case so that's a consideration.
Calls:
Bose only works on the right ear. I don't know why they decided this was a great idea. Jabra works on both but I've been having issues with this for some reason. The first call usually doesn't work straightaway, the person on the other line can't hear me. I have to call back then it will work. This is very annoying.
I don't believe there is a clear winner here. Both have their positives and negatives. If there were other ear tips available in the market for the Bose that fits me better, I'd probably choose to keep this. But from what I've seen they're all designed exactly the same.
I'm sad no one has chimed in yet, but thanks for the review! It's always good to have hands-on reviews by people who're using these day-to-day. Even if one review in isolation may be subjective and not widely applicable or useful, a larger body of such reviews would lead to a more consensus view or opinion of products, so thanks!
