It is not to say that Primary technology isn’t very good. If you have a relatively sedentary lifestyle and you want the hearing aids to hear the TV and radio clearly and talk to small groups, well then, Primary technology could be ideal for you. This level of technology may well give you some help in mildly noisy situations, but once the noise raises beyond that, they will struggle. However, if you pair these devices to a remote microphone, you will find that you get a bit more help.
