If anyone told me that they had people in their office who were so loud on the telephone that Bose QC20 noise cancelling ear buds (turned *on* -noise cancelling mode- and pressed in with a good seal) *and* music turned up to the first "amber warning" bar on an iPhone would be insufficient to render them inaudible, I wouldn't believe it.
I *do* believe it, however, as I'm experiencing it first hand.

In a good mood, just incredulous.
