Hi, I am from Taiwan. Recently, my PartnerMic stopped working, and I was quoted a repair fee of USD 350 by Phonak Taiwan. However, the original price I paid at Costco was only USD 190, which I find quite unreasonable.
Therefore, I am considering purchasing a Phonak PartnerMic through eBay instead of the Costco version. Could you please confirm whether the Costco Phonak Brio 4 hearing aids are compatible with the standard Phonak PartnerMic?
Thank you very much for your assistance.
