Like many, I was excited for the release of the Incipio Atlas, but after receiving it, was disappointed. The sound quality through the ear piece was terrible and I had issues with the screen not being sensitive in the corners. But I really loved the case and wanted it work. I believe I found a fix for the "Kazoo" in the ear piece as well as a fix for those having screen sensitivity issues. The Kazooing seems to be a resonance and back feed from sound waves impacting the membrane and then bouncing back off again causing a "buzzing effect". With some experimentation I found that these two small pieces of material drastically reduced or eliminated the issue. Your results may vary but please give it a try and post your results. I also found turning on "hearing aid" in the Iphone settings helped with volume as well. The addition of the microfiber cloth to the back of the phone helps to even pressure placed on front of screen thereby making the sensitivity what it should be. List of items for fix, Old microfiber cloth razor knife masking tape Steps; 1. Use razor knife to cut out a piece of microfiber cloth approx. 1/10" x 1/2" (pretty small) 2. Use Razor to also cut a piece of masking tape approx. 1/8" x 1/2" 3. Place front of Atlas Case face down (glass down) and find the earphone port. (elongated slot with meshy stuff in it) 4. Using a fine pointed object (like the tip of a knife), place the small piece of microfiber cloth onto the earphone slot. Using the tip of the knife, gently push and tuck the microfiber into the earphone slot making it flush with the case. 5. Place the small piece of masking tape over the earpiece hole covering the microfiber cloth. The tape should cover the ear piece only and none of the other cut outs. 6. Insert phone into case. Make sure to pull out right side of case (where mute switch is) until the case clicks and the arm on the switch "grabs" the mute switch on the phone. 7. Cut a piece of microfiber cloth approx 3.5" x 2" and place on the back of phone before putting Atlas back on. Make sure camera and flash not covered. 8. Place back of Atlas case on and snap into place.
