I'm so confused, mine is really really noisy - a loud whooshing like the Tardis with every breath in and out. I've pulled it apart and put it back together and can't work it out. Would be great if you could demo it actually on a person in action so we could see and hear it properly and be able to compare it.

This happened to me too. I found I had a leak in my mask.
