I have Jabra bluetooth headphones (full-size, not earbuds) and have taken to turning off Bluetooth on my MacBook to get them to work on my Windows machine, which will connect but not play any audio through them otherwise. Some device pairs work fine, some work fine until the other device plays a sound and then can't recover, others (my Windows gaming box) just don't work if something else is connected at all.
