The Custom-3 is superior sound-wise because of the separate drivers and crossover, which is why they are priced higher than the 1 and 2.
The Image is in a separate product category, design-wise. It is a single driver and not over the ear, and although it has received rave reviews for sound, I wouldn't compare it to Custom-3. The cost is relative to the intricate (ie: super tiny) design, and the difficulty in building them and the expense of the technology used in doing so. The value is not only in their sound, but the small and ultra-comfortable design. And yes, the Custom models are also comfortable, but, personally, not as much so because I do not like wires around my ears. Again, that's a personal preference.
I hope that helps a bit!
