... Like sunglasses, occasionally replacing is part of the program.
This is a key observation.
Thing is, the main thing that breaks with earphones of any type is the cable, and most often the cable breaks at the point where it enters the body of the earbud within the strain relief. Using earphones with MMCX connectors to attach the cables almost completely eliminates this mode of failure, by not only making the cable alone replaceable, but also allowing the cable entry to rotate so it doesn't get broken by twisting.
With BT earphones, the next most common failure is the battery. In that case you just throw them away. Again, using high quality earphones with MMCX connectors and a replaceable BT module allows you to replace just the broken part and keep the earphones themselves, so if you have expensive or high quality earphones, they are not a loss.
I have had my SE315s for over a decade. Just like my Oakley Crosshairs (two pair!). So for me, I don't mind investing more in high quality stuff I won't have to replace every year, but that depends on my ability to keep from sitting on my sunglasses or stepping on my earphones, or losing either of them. When I go on a vacation to a third world country or on a business trip to Las Vegas (back in the day, eh?) I don't bring either of them because I don't want to drop my Oakleys off a cliff in Belize or leave my Shure earphones in a hotel room after I check out.
That said, the above FiiO RC-BT module costs about double what a pair of Skullcandy BT earbuds do, so when the battery goes south on the FiiO, it will cost more to replace. But IME the strain relief end of the cable will not break. I've had my FiiO now for about 1.5 years using daily, and I mean often, daily. They have outlasted other BT headsets probably three to one. But If I really was doing things that were abusive to BT earphones, I would buy a set of more disposable ones like Skullcandy to keep my more expensive rig from unnecessary risk.
