Yes, some makes and models have a lower tone pitch and some might be louder in volume, but I also think a lot of what you're perceiving is due to the camera's microphone pick-up. I have made some brief hunts with only the Apex's speaker at work, but most of the time I use the MS3 wireless headphones with the volume all the way up, except the Iron Audio Volume at '3' or sometimes '2.'
