I wish to buy a Bte ear hearing aid for personal use. The one I've in mind is as follows: Mars 16 Ric / Bte Ear Hearing Aid Equipment, 16 Channels Medical Hearing Aids. I'm at the moment using a Siemens Bte hearing aid model Lotus 23 sp. It's effective at quite places without back ground noises. Will the one I wish to buy superior than the one i'm using? Could you kindly refer me to a company which is selling the mentioned hearing aid in China especially in Guangdong. Thank you. Show More
