Thank you for viewing. Please read the profile. This is a GEO (Geo) fully wireless earphone (GRFD-SWE100M7 NB) in navy. I am selling it because I am replacing it. Both the left and right plastic tubes are cracked. I had them replaced once due to a claim after purchase, but they cracked again. There was no dropping, so I think it's a design issue, but I will sell it as junk due to the above reasons. There was no problem with the use. It was working normally before listing. I cannot answer any questions regarding how to use it. Please handle it yourself. Other notes: ◎ It was stored in a chest of drawers at home. Since it is old, there may be slight stains or scratches. Please understand that it is a used item before purchasing. ◎ Please check the details in the photos. The color may be slightly different between the photos and the actual product depending on the environment, please understand. ◎ To prevent trouble such as "it was different from what I expected" after the product arrives, please ask questions before purchasing and make sure you are satisfied before purchasing. #FullyWirelessEarphones #Bluetooth #Bluetooth #HandsFreeCall #Waterproof #IPX4 #AACCompatible Other features...Junk
