Jawbone Bluetooth or equiv small speakers. Any others that may be better?

My little Jawbone travel speakers finally gave up the ghost.  They sound like they are playing through a kazoo.  I have always liked them.  Nice and small and do the job.  Before I replace with the same item, curious if there are other speakers that folks like better for some reason.  Things I like:  They broadcast from the front & rear. So if placed right, sound much larger than they are.  The battery lasts a reasonable amount of time.  The size can't be beat for travel.
What could be better: Bottom could be stickier so it doesn't move around so much.  Other than that I dig 'em.
Thanks all, John
