I used to have collections of both analog and later digital hearing instruments, however, none of them were satisfactory to me, they went out tune all the time, and weren't comfortable enough. These new Oticon hearing aids made a whole revolution for me, I and stopped sliding me from getting into social isolation causing by lack of ability to be in noisy enviroments. And the devices just work perfectly, gently combining natural sound with digital help in those frequency I lack in my hearing, many thanks to Cubex for an excellent and caring service as well without which all this revolution would be simply impossible!
