I am all for recycling anything possible, but I have never seen any type of ear buds or headphones that are disposable- I use electronics until they quit, or give them to grandchildren when I upgrade, and then dispose of them at sites that accept electronics. I certainly use mine enough that they are worth buying.
Thing with wireless headphones is the battery lifespan mostly determines the life span of the product. The speakers may still working perfectly fine, but when the battery decays, so does the product. That is unnecessary waste when the manufacturers could just provide methods to detach the battery, without damaging the headphone itself. I may keep using the headphone longer, and I am willing to buy the battery replacement pack instead of the whole unit.
