These are fantastic!I have had these for about two weeks now, and have had no problems whatsoever with ear sensitivity. My ears are sensitive to nickel, copper, and cheap metal earrings.Use and FeelThe earrings go on easily, fit well, and do not fall out. They are comfortable, and surprisingly light weight considering the amount of metal on them (I did a little research, and Titanium is a lighter weight less dense metal than silver or gold, thus the light feeling).Good for Sensitive EarsI wore these in the shower and while sleeping for the last two weeks, and only took them out to gently clean them with a salt water solution every other day. Have had no side effects or swelling or itching in the ears. Very safe for my sensitive ears.AppearanceThese are very beautiful. The picture does not do it justice. I am bad at selfies and so sorry but had shaky hands and the picture came out blurry. Anyway, they are very shiny and have a simple elegance to them. I had several compliments about how I looked "pretty" in them while wearing these earrings.I purchased the rose gold ones. The rose gold plating was only on the very edges of the outside of the earring, and all surfaces of the earring which came in contact with my skin were titanium.Very happy with this purchase. Considering purchasing again in the other varieties in the future.P.S. I noticed there was another review saying they were bent. Mine were not bent all and lined up perfectly, snapping together well into the ear. I think perhaps the other reviewer meant the insert was bent? The part that goes into your ear is a curved semi-circle shape, because the entire earring piece is a circle. This is to be expected and normal to fit the earring together to snap it into place.These have become my everyday earrings. They are light & being titanium they are truly hypoallergenic. I love the fact that they are gold & silver & go with whatever other jewelry I wear.They are super cute, and I like how they feel. I wore them for about five days straight and did not have the slightest reaction (my ears are very sensitive). However, the hinge is very loose and they kept falling out when I got changed or bumped them in any way. I don’t want to lose them, so that makes me not want to wear them which defeats the purpose.Really pretty and did not bother my very sensitive ears.The earing feel good, not to heavy. They also have a nice appearance. The only thing I do not like, is the clasp the holds it closed is too weak.I bought these for my daughter. They look really cute and pretty on her. She had NO ALLERGIC REACTION, so that was great because other earrings I gave her did cause this.I LIKE!!!I wish they also came in silver I am very sensitive to metal. I can wear these for hours
