A:Answer Heck yeah. Its what makes them have superv bass. Anything lower than 20, makes for great bass. The lower the better. As for the higher end, i can't hear passes 17,000, so it doesn't make a difference for me. For those kids that can hear that "mosquito" sound, they will benefit the most. Human hearing can only do 20-20,000. Anything outside is extraordinary. If your looking for performance, aim for the hd audio, but if you fending for bass like i do, then these are for you.
