The units arrived on time and physically in good condition with all accessories, but visibly dirty, the seller did not clean the units or the earbud silicone inserts before shipping. Earbuds themselves were capable of functioning as well as the case, but would not connect to each other. In order to pair them to the desired phone, I had to manually turn them off, manually turn them back on, and manually set each one to pairing mode. They will not connect to each other right out of the charging case (as they should be able to) and will not connect to each other even with a full reset of the earbuds. Disappointed in this particular unit, but willing to try again with a different seller and unit.
