Trouble with simple Audio

So Im trying to add sound effects to my game, it sounds 1:1 on the browser, but when I test it on ios...it suddenly becomes high pitch and the bass seems removed..The sound is a heavy boom gun shot, and it like a toy-gun now..lol

I even bought the sound bundle for C2, and it doesnt sound 1:1 either..

Any ideas guys? =/

Thanks!!!!

Are you sure it's not just because mobile devices have small, tinny-sounding speakers? Hard to get a subwoofer in something the size of a smartphone.
