This is just what I needed, almost. My only issue (and I'm sure it's more of an issue with Plantronics than the seller) is that I couldn't get just the size I wanted. I needed the replacement because my ear bud fell off my headset and got lost. I would prefer to have 3 of the size that I use rather than buy 1 replacement and 2 buds I don't need. I do appreciate the low price and quick shipping.
