Let me share my headphone advice for those encountering issues charging the wireless Equinox phones, or the miccus equivalents like I bought. I live overseas so warranty work is hardly worth the trouble. I beach hunt and did so carelessly for months until the charging issues emerged. My guess is sand and salt water made their way into the micro-usb charging port and corroded/damaged the leads inside. I was about to give up on wireless and use it in wired configuration, but I managed upon a solution that has at least delayed that inevitability. Every time I need to charge, I use isopropanol, a high octane alcohol (99.8) and a toothbrush to scrub in the charging port. I repeat this three times. This cleans corrosion off the leads and it dries without residue. If a cable is suspect do the same on its connector as well. I have brought the phones back to life with this trick at least for a while. Another important thing is to put a small piece of electrical tape over the charge port on the headphones. I also cover the headphone jack, the little hole nearby, and the volume buttons as well, but the critical one is the charge port. I imagine this keeps some salty residue from making it to the leads. Anyway I hope this information is helpful to somebody.
