Dakota316 - did you own a LP Fre case before the Obex? If so you are just experiencing paranoia from owning the Fre lol. I do not have any rattling through the speaker.
LOL You sir are correct. I did have a Lifeproof case. Believe it or not, after going through a few replacements I got a good one. Version number I honestly don't know, but the back piece does not have the clear glued on pieces, its just the 3 pieces that were already on the back are a bit more raised up, and the sound rattling is nonexistant. I am just giving this case a shot, and it may be just paranoia because my cases before the final Lifeproof I got were TERRIBLE for sound. Gonna give this case a few days and see how I like it, but so far its pretty dang good. Will take a bit to get used to the dots on the screen, but its something I can get used to for sure. At least I wont have the oil slicks all over the place, lol.
