It's only really meaningful in scenarios like a recording studio where the performer is listening to themselves live, in headphones, if the signal undergoing A/D and D/A conversion with some processing in between. It could mean 2ms instead of 8ms, which can be the difference between distracting and not. Not relevant here (I admitted "not applicable") but just an example of where some utility does exist, but the utility is definitely not audible frequency response.
