These hearing aids are for sale in fully working order and in excellent condition due to lack of use, they have been checked and sterilised and had new guards and tips put on so are good to go, these hearing aids connect by Bluetooth and you can use on the Phonak App to change settings to suit you, these cost over £3.000 when purchased so hopefully someone will get some use out of them, ideally you need to check with your audiologist to see if these are suited to you and they can set them up to suit your own personal hearing requirements, not sure when these were purchased or from where but they are not that old, make an offer and any questions just ask, thank you.
