London Underground announcements in certain stations seem to break Bluetooth really frequently. I suspect that at some point, the message is being transmitted by radio and this must be at a frequency that interferes. Also seen on platform WiFi messed up in a similar fashion - this causes the most grief when calling over WiFi kicks in, you make a call only to find it get wrecked the moment they start announcing. Luckily in some stations you actually get a better signal over mobile, so simply turning off WiFi resolves the problem.
