Yeah like Digit said there's not truly a consensus on this. I'd link you one of multiple threads on the matter that's been posted here before if the Search was currently up and running. Some people will always be annoyed by it, others think it's cool, and I think the majority would probably fall somewhere in the middle. Just keep it tasteful and toned-down unless you're outside or in the middle of a themed shoot/gathering/etc and most people won't have any issues with it. And sometimes you'll find whatever speaker you bought isn't even strong enough to be heard over the din of a con anyway. My friend used a little Bluetooth one and turned it off early 'cuz even she could hardly hear it.
