The Q-series doesn't make as much noise because the kinetic particles are confined to 4 small chambers, so maybe they would be better for someone with really good ears.
I've played the 7g, 5g, Ki5, Ki15 and now the Qtour and never been able to hear this sound people talk about. PK's are just great playing tennis racquets that happen to benefit those with TE.
I don't know, maybe my hearing is bad and I'm just not aware of it !
