Here's what I like and don't like about my CIs:
Likes:
Being able to hear in noisy environments
Being able to understand the TV and radio
Being able to use the phone
Listening to music and hearing it better than I ever have before
Fuller, richer sound quality to voices and environmental sounds
Being able to hear and understand the voices of women and children
Listening to talking audio books
Being able to hear high frequencies I haven't heard in 20+ years
Being able to hear environmental sounds such as birds singing, clock ticking, thunder, rain, leaves underneath my feet, wind, etc.
No longer having to rely on a tactile interpreter or captionist for communication
No longer having to deal with the frustration of progressive hearing loss from year to year
No longer having to wear earmolds or deal with HA repairs
Dislikes:
Having to change batteries every 5 days
Adjusting to new maps
The loudness of sounds and voices when my first CI was activated
