Jerome - I was actually planing on writing a short follow up post about this case.
It's fantastic! I have zero audio problems with calls - everyone can hear my fine, both on and off of speaker. The actual sound volume is a little reduced but that's to be expected with a waterproof case. I personally love the screen protector-less design. I'm careful with my phone but I can't always rely on the weather to do the same. I have been caught in 4 storms these last 2 weeks and, obviously, my N??d has performed like a champ! I am extremely picky whenever it comes to iPhone cases but this is a hands down winner for me! The protection and functionality this case offers can't be beat.
If I had to post a couple negatives, I think $80/$90 for a N??d or Fre is kind of ridiculous (I had horrible pillowing with my Fre and took it back immediately - a case that expensive should be PERFECT in my humble opinion). The bottom lightning port door is very difficult to open (which I guess could be a positive because its truly water tight). If anyone has particular questions or requests, let me know!
