Pairing is famously a UX nightmare [0]. Even Apple's AirPods cut out constantly, suffer from interference from other nearby devices [1], and apparently just don't work in an open space [2].
To people with Bluetooth expertise: Why is the Bluetooth audio experience always so...bad? Are there some fundamental technical limitations in the spec? Are my expectations unreasonable? Or is it just always implemented poorly? Followup: are there competing technologies that Just Work™?
