Ordered a set of
Parasom A1 buds.
I've had them for a few days now and like them so far. I'm a fan of buds that have a volume control on them. I don't have Jbirds to compare to but I hear a good amount of bass from these and they look very much like Jbirds if that matters. All the different sized cones, wings, and ear hooks should make them fit for most people. For $30 they are pretty good.
I also have a pair of
Mpow Seals. These take some getting used to as the first couple of cms from the bud is made of a stiff metal that bends to loop around your ear. They are a little more fiddly to get the buds and the wires aligned in the right place and the buds are a little larger. Once in place though, they don't move.
Between the two, I think the Parasoms will get more use. The control module on the Seals is smaller and therefore maybe better for workouts and such.
