FWIW, 31 msec is a lot of delay by audio standards. I've seen reports of 
half as much delay being bothersome to musicians listening to their own 
voices in headphones in a recording studio. 

A delay of 35-40 msec just about the limit of what is generally tolerable 
to a performer on stage, and often happens when loudspeaker systems are 
suspended high above a stage. That's ONE of the major functions of a stage 
monitor (those speakers on the stage, or in-ear ear monitors) -- to 
provide the performer their own voice with less delay than the main 
system. Few of these systems have zero delay though -- 5-10 msec of 
latency is typical of the DSP used in modern pro audio systems. 

Bottom line -- at 31 msec, I can see why some are bothered by it and not 
others. The perception of delay varies from one person to another, and 
also depends on program material. 

73,
