Bose QuietComfort II Wireless In-Ear LEFT Earbud Replacement Tested

NAVY BLUE. These are in good to fair condition, some have signs of wear scuffs, dings, minor scratches etc. Item is used and was tested to work excellently as a stand-alone earbud. PLEASE NOTE THAT WE ARE NOT SURE ON HOW TO SYNC THIS LEFT SIDE EARBUD WITH AN EXISTING Right SIDE EARBUD BUT IT CAN BE USED AS A STAND-ALONE EARBUD. ( I think these can be paired and synced if they have matching serial numbers. This is a 4 digit alpha numeric found under the rubber / silicone ring. The one that says IPX4 is just for waterproofing, the other number under the square bar code is the number you want, message me that and I will see if I have match before you buy!!!) This listing is STRICTLY for this original replacement working LEFT side earbud ONLY as shown with its attached ear-gel and mid silicone cover as shown. We try to clean these as best we can but sometimes they have some earwax as they are used earbuds. Message me with any questions!
