I too have a cochlear implant with the 2.5mm jack adapter, and I actually prefer headphones to the jack adapter, mostly because the color of the sound seems to be a lot better with headphones than the 2.5mm jack - the direct audio signal seems harsh and not warm. I listen to a lot of classical rock, and this may be part of the reason, it just seems to translate better over headphones than direct input.
