Price for custom molds (RIC)

Yes it’ll need to be soft silicone, and there’s very little movement at all, sure periodically I would push the receiver in all the way just be sure it was sitting how I wanted, but it definitely didn’t make any difference to me because it’s just mm in movement.

Yes, this is correct. When it comes to RICs, the embedded molds can only be used with hearing aids that share the same receiver–sister brands included. So for example the unitron venture can be swapped onto the phonak lumity but not the phonak infinio which uses a new receiver. However, the software won’t necessarily detect across manufacturers, so for example the phonak software may not pick up the unitron venting code.

The friction fit and collar fit are both more flexible but it kind of just depends on what fits with trial and error so you can’t count on it. Friction fit is often more forgiving, but still technically made for a specific receiver.

BTE molds are cross compatible with all BTEs.

Any tips for doing DIY using a dome or mold that is not defined in the fitting software? Do the selections matter or will in-situ account for everything?

If being fit with REM, should the provider select the correct dome/mold if possible or will REM account for everything?

Pick the closest thing and then fit to preference? DIY is all just fitting to preference anyway isn’t it?

With REM ideally you should select the closest thing, but you can wrangle around anything with REM it just takes longer.

That sounds extremely painful!
