I think what you saw is typical in a pair 15x70s. I have a pair purchased from Burgess Optical and see the same thing you are seeing when look at Jupiter. I have no problem seeing the four moons, but never get a clean image of the disk. I think what this type of binocular is good at is scanning the Milky Way, viewing OC and maybe some double stars. I never intended to use mine for planetary or lunar viewing, so my expectations did not fall short. What I was surprised at was being able to see galaxies, such as M104.
Maybe some others can lend advice on lunar and planetary viewing with binoculars.
Hope this helped,
