Why aren't they happy with it?
"Do you want to hear or do you not want to hear" isn't much of a question.

Cause if it's the first one, that's called hearing neutral
No, it's also a common problem with hearing aids. There's something about the way that background noises are amplified and electronically processed that means your brain can't filter them out the way it can with normal hearing. Both hearing aid and cochlear implant users often become functionally deaf in settings with lots of background noise, like restaurants, and certain sharp, high-frequency sounds, like cutlery clinking, can be over-amplified to the point of being physically painful. The hearing aid users I know remove them and either rely on lip reading, people shouting in their ear, or just put up with not being able to engage in conversation because the device becomes so useless and uncomfortable in noisy settings.
Mind you, I know next to nothing about deaf people and their s**t, but I remember learning about something in psychology where your brain learns to filter out loud noises after it's exposed to them enough. Maybe the problem is that they don't keep it in long enough, so their brain doesn't have time to adapt to those noises?
Again, I know almost nothing about this device except that it lets you hear.
I think the problem is inherent to the technology, as it persists even in lifelong users of the cochlear implant. They have been using it to hear as long as a person who can hear unaided has, so you'd expect that they'd had the same amount of exposure. I don't know the cause of it, or even if the cause is understood by anyone, I just know that it is a phenomenon that exists: people in general using an electronic device such as the cochlear implant or a hearing aid are not able to filter voices from background noise the way a person hearing unaided can.
The quality of sound experienced through a cochlear implant has been described to me by people from the company (my research group has close ties with cochlear) as "its apparently a bit like listening to a tinny old radio through a tin can on a string." It's far from perfect, natural hearing. Have you ever heard an old .wav audio file recorded in a noisy setting -- like the audio to an early digital video camera recording a big christmas dinner or something? That's what I imagine it's a lot like. >.<
The hearing aid users I know have previously had normal hearing, but have experienced a reduction in hearing level as adults through age, disease, or occupational noise exposure, so they would have previously had the ability that people hearing unaided do to filter voices from background, and it hasn't carried over.
