I was considering buying this phone, and I have hearing loss. Typically I prefer for my phones to have hearing aid support, and it definitely impacts my decision towards buying this phone.
There is the association of hearing aids in accessibility but not having any myself, I can not tell you more.
On the other hand, if you want to buy this phone and not primarily use it for games but for general use then I think it's not a good choice, all phones with an 888 for that matter.
I was going to use it for games, I don't do much other than play games and talk with friends.
