Havent had any issues. fungal ear infection, no doubt! I was able to fit 6 hella 700ff lights on when installed on 89 Bronco The one with the money symbol that people speak of in these reviews obviously refers to placing family/the lives of our children OVER money (family over money). I put it back in the case and then reinsert in my ear and it plays for a few seconds and then cuts out, sometimes stays off, sometimes cuts in and out. Summary: I wouldnt buy them again, and, if Id tried them on in a store, I probably wouldnt have bought them if there had been a better choice. The sound is nice and clear with bass just how I like it. I love how spacious is as well. Comfortable wear. Due diligence and a desire to be able to use one earbud at a time drive me to search Amazons best rated under $50 TWS sets, and Tozo looked pretty good.
