I haven't seen any reviews for this case yet for the S4. I'm looking to replace my Obex case (the closures for the charger ended up falling off due to the rubber tearing) and want a waterproof one. I've seen most reviews for Lifeproof and Otterbox saying there's issues with the sound. The past reviews for their iphone case I've seen said there's no issue with the sound. Any other comments on this? Thanks for your input!
