IEM and cable question

I have truthear novas and the audio cable is detachable from the in ear monitors. This is fine except for the fact that they seem to be extremely flimsy and easily detach.

I’m admittedly new to IEMs and not sure if this is the norm or not. But I was wondering if this is normal and if there’s anyway to help rectify it?

The novas sound great however I don’t have much to compare them to, but would like to see if anything can be done about the cable constantly coming off.
