Sorry to tell you, but I just changed from the RIC 85dB receivers with bass domes to the RIC 105dB receivers with custom clear acrylic molds, and while the earlier (RIC 85dB receiver with bass domes) can’t be seen at all from the outside because it sits deep enough and completely inside the canal and only the wire is seen, the later (RIC 105dB receivers with custom molds) is just as big as the CIC, so it’ll be just as conspicuous as the CIC. And on top of that you have the wire going from the HA behind your ear into the door of the custom mold. With this wire, the RIC custom mold is even more conspicuous than the CIC. No matter how small your receiver is, the custom mold needs to take up all the space in the canal, then some right outside of it as well.
See the pics attachments here to get an idea.
