Does anyone else with a Nexus 5 have a charger that emits and audible buzzing noise? It's not deafening or anything, but you can easily hear it across a quiet room. Other USB chargers I own emit a noise, but you pretty much have to have your ear right up against it to hear anything.

I took the first one I got back to the store (PB Tech) and the tech there said it shouldn't be that loud and they would replace it. But the replacement buzzes just as loudly. Not sure if I have just been unlucky, or if this is the noise they all make.
