In the world of headphones and IEMs, anything from any brand can fail. But if they don't fail within a week, and no accident happens, the item is likely to survive at least a year ( except non detachable cabled ones)
For inexpensive IEMs like Blon, T2 etc. I will take the risk of no warranty ( 7 days warranty/ DOA warranty)
But for expensive stuff, will think... specially with hifiman...I will register the headphones immediately to even get the additional 3 months warranty ( In EU it's mandatory to provide 2 years warranty for any electronic products, and the process for application is very simple and works nicely, even for products from China / US with one year warranty)
Chinese companies like Hifiman are far better than US companies like Audeze and VModa.
I fought with both of these companies over phone multiple times, threatened them and eventually got partial refund from both.
Hifiman, though had their QC issues for years, was very professional with me, I was probably the only one from Czech Republic who was buying stuff ( and returning for repair) from them directly for years. Unlike Audeze/ VModa, they always provided me with a local address where I could drop the product for repair and the kept on giving 10-20% discount coupons for their next product for year after year
But when it comes to warranty, Sennheiser is the best by far ( but you must have a physical copy as proof of purchase, without it, they won't touch your product)
But they will do everything else to help you as quickly as possible. And most of the time they will replace your product with a new sealed box.
They don't do serial based warranty check up as their is frightening number of fake Sennheiser products with copied serial numbers from retail box ( please be careful with Sennheiser's IEMs)
Beyer is also great with warranty.
Other than hifiman/ Sennheiser/ Beyer I'm perfectly happy to take a chance with inexpensive IEMs or headphones.
Amp's warranty is very tricky...but that's for another day. If you have SMSL/ THX amps, read their warranty policy very carefully.
@quaratineinthesejeans can suggest you something better in chi-fi iems, also consider Sennheiser ie40 along with chifi.

Sorry mate, I am not very up-to-date with IEMs and stopped buying expensive in ears. Found the wonderful Etys after coming back from India, and using them after a long long time.
After the disappointment with the older Andromeda, sort of gave up on them. It's probably my ears..don't like the smooth treble of Andromeda, it makes bad recordings sound decent.
