Seems to me that the baseline assumption should be if you spend more, net, on the wireless (or wired) headphones, the environmental impact is probably greater.

A million reasons can be given why the cost isn't exactly proportional to the environmental impact, but any time someone starts by assuming it's unrelated, I think they are probably not making good decisions.
