I'm reminded of a quote: "the best camera is the one you have on you." People ditched their digital cameras en masse when smartphones became popular. Not because the smartphone cameras were better, but because they were convenient.
The market has spoken. People drastically prefer the convenience of Bluetooth over the quality that comes along with having to constantly untangle wires or having audio cut in and out from failing wires.
On top of that, universal adoption of noise cancellation has resulted in dramatically better quality in practice than what people were using in 2005. Yes, wired headphones with noise cancellation are even better, but not to a point that people are willing to sacrifice the convenience of going wireless.
