I was so excited to find these online and after reading the description and few reviews, I was sold. Although a few of the reviews do say, they pinch, they do. But, at least for me it took maybe about 4 hours or so to finally notice the lvery light pinching and even then it wasn't hurtful at all. Ive worn these at about 6-7 hours at a time, at least only on the weekends when I go out. Anyway, the first day I put them on, it was fine but then I felt a bit of itching. The next day I put them on, it was ok but that same night the itching got worse and the next day, I got an allergic reaction to the magnetic metal. I have always been used to fake jewelry and anything with nickel in it. I guess this also gave me an allergic reaction, I got red circles and scabs. Its been almost 2 weeks now and they are almost healed. After reading online on how to cure this or get over it, the best option I found was to put a liquid bandage/liquid skin on the metal and inner part of the plug where people cant see. Also I put a bit on my ears. Its a pain in the butt because I will have to do that every other time I put these plugs on but thats ok. It compliments my outfit anyway. ;) So case and point, if you are allergic to metal don't get these unless you want to adapt to my solution. Its better than throwing away $15 and/or never use them. Too bad I am not allowed to get real plugs, well I don't want giant holes in my ears anyway for life. Enjoy!
