Unfortunately, you gotta think about these things. My personal story is that I dislike that Bose no longer makes their QuietComfort 15 model. It's corded, active noise cancelling, and it's powered by an AAA battery. As far as headphones goes, this is BIFL because you can fix it when something goes wrong. It's too bad there isn't a good substitute for the QC15 because I love the product.

Planned obsolescence is a system in many devices, because a product that works forever does not create profits for the manufacturer. In the current devices, PC and mobile, this obsolescence is no longer so pronounced and the products last for many years in good condition, because in these what leads to their death are not the devices as such, but rather it is produced through the software and the compatibilities, which force to renew these devices. In printers, obsolescence comes through ink cartridges, on the one hand with exorbitant prices and on the other hand, if the manufacturer wants to sell a new model of printer, they simply stop making the cartridges for the old one, turning the old printer still in good condition, in a useless paperweight.

Plenty of electronics are practically zombies right off the production line.
