My girlfriend is getting rather deaf and needs good hearing aids. Until now she has made do with pretty cheap things that keep conking out after three or six months, so I want to buy her some good hearing aids. 
Anyone have experience with shops in Bangkok that sell them? Any recommendations?

I have consulted with these guys, about CIE, but they also do traditional hearing aids. They have many branches.

Eartone: Ear, Hearing Aids and Balance Medical Center (Sukhumvit 42 Branch).  https://www.eartone.com/index.php

I have not used these guys, but they came on my radar a few times

I also purchased mine from EarTone. 

Starkey hearing aids are sold, cleaned, and repaired at the Audimed center in Bangkok.  Please see: https://www.audimed.co.th/

I bought Starkey hearing aids in the U.S.  These are cleaned and repaired at Audimed.

Agreed.

Audimed also do Oticon which is, in my opinion, the rolls royce of hearing aids.

I am intimately familiar with Adimed having been a customer for quite some years now.

They also do AB cochlear implants but a better choice would be Med El which is also in Bangkok.

Thanks for the info, guys, that really helps a lot.

There is a largish store on Sutthisan Winnitchai.

I noticed it on a walk bc my mother uses hearing aids so it stayed in my memory.
