I am selling these because they didn't fit my ears. I lightly tried on the black ones to check the fit, but I opened the other colors to test their functionality. I confirmed that pairing works with all of them. I replaced the black ear tips with ones of the same color. Please contact me if you'd like to buy them individually.
