Most of the issue stems from annoying dongles that wired headphone users typically don’t want to carry.
The situation with fairphone is especially infuriating however, as omitting the headphone jack goes against the whole point of fairphone IMO.
Bluetooth headphones, as convenient as they are, have integrated lithium batteries, which are harmful for the environment. They also have a very short, finite lifespan. Despite these issues, fairphone removed the headphone jack on the fairphone 4 and 5, while simultaneously releasing true wireless Bluetooth earphones that are not repairable. Their whole brand is based on creating ethically sourced, repairable products, so offering an inherently unrepairable item for sale is rather disappointing. I am aware that they offer over ear headphones that are repairable, but I think they shouldn’t sell true wireless earphones until they come up with a real repairable design.
In contrast, there are wired headphones from the mid 1980s that are still functional and still sound amazing, even if they aren’t as convenient to use. There are also modern wired headphones and IEMs (In-Ear Monitors) that have removable, standardized cables. This is great since the cable is what breaks on wired headphones 99% of the time.
