I regularly used my Westone UM2 now for 4 years. At the moment they are in my sport-rig. If you handle your IEMs with care I would say, that they can last at minimum 5 years or even more.

...Out of curiosity I contacted my Audiologist friend who has many decades of experience.
His reply, via email: "As far as balanced armatures going bad after 7 years, I have never heard of such a thing and certainly do not believe it to be true. Balanced armatures come from the hearing aid world and I know of many hearing aid clients that wore their old analog hearing aids for 15 years without need for repair. While the average lifespan of a hearing aid is only 5 years, the figure is this low because of the age of the clients using them and developments in digital audio processing."
In other words, there is no inherent limitation in lifespan for a BA driver per se.
Cables, earwax, and many other issues are of course still a factor, as is change of preference or desire to upgrade.
