Couldnt do the hearing test on my own, the writing is small. Fine since he did it.

Sorry the text was small for you. You don't have to use the app: ring us and we'll run the hearing check with you over the phone and set them up from that. Same for anyone else reading this.

Noticeably. Might be my ears rather than them, I dont know. Adding a picture, they look identical to me...

Please do get in touch. When one side reads noticeably weaker after the check it's usually the fit rather than the device, and it's a two-minute thing to sort out over the phone.

Four or five hours and I want them out. Not sore, just aware of them the whole time.

The sound is good, I have no complaint there. After about six hours my ears ache and I have to take them out.

Everyone else seems to manage in a few days. My own voice sounded wrong for ages. Alright now.

I have gone back and forth on this review for a month. The facts: television better, telephone somewhat better, one to one conversation better in a quiet room. Group conversation no better at all, and outdoors on a windy day worse than nothing because of the rush of noise. My loss is on the moderate to severe line and I suspect that is the explanation, and the doctor said as much when I saw him afterwards, which I should have done before ordering rather than after. Three stars because they have genuinely helped in the house and I am keeping them, but somebody in my position should know what they are getting and not read only the five stars.
