Untested, these are sold as replacements to ship in to Apple when you are making an AppleCare+ claim. These are in good to poor condition are assumed to be broken but are untested.  Some of them charge and pair, some of them have static. i'd say about 5/8ths of these work and pair but have static in the transparency mode / noise cancelling mode.  Ships fast and free! Message me with any questions. Doesn't necessarily have the eartip but if you want one leave a note on your order. These are dirty but can be cleaned up if need be
