Appreciate the water proof clarification. It's really a shame they removed the jack, because I still very much prefer to continue using my wired headsets, not because I mind spending few dollars now and then buying these adapters when I invariably lose them, or the additional complication. And some of the non oem substitute adapters are of really poor quality and lose contacts when moved around. I currently have a Motorola Z3 Play phone which I absolutely love because of it's moto mods options that let me have a slim second battery literally making my phone power last few days, a quite useful projector, a JBL speaker or a true Hasselblad camera. Talk about James Bond style devices! LOL.
