why does Bose have such good earbuds but such terrible Bluetooth connection

This post probably it's allowed but still, the have the Bose QC 2 earbuds and the connection is the worse i've ever experienced with any Bluetooth anything, I just don't get it, the Bluetooth is terrible on every Bose device that has it. It's so weird that they make very good audio and Anc headphones and earbuds, but the put absolutely no work on their Bluetooth chips
