Sending a very important tip, never buy hearing aids without actually need, and when I say this, I speak of the example of my wife, we spent 2400.00 euros in two devicesthat literally are useless, because even using it, continues not understand what you talk to her, unless very close to her speak slowly and clearly, the devices only amplify external sounds, but to hear the television for example, she can not understand anything of what is said, only serves to even hear it beep watch, ring,and sometimes the phone but the phone rings she does not hear well, so forgethearing aids are an unnecessary expense ...

 Do not forget, this is a lie, no works even as they say ...
