Wireless earphones mare, waterproof IPX6, compatible with Bluetooth 5.0 + EDR. - Model Name: mare - Bluetooth Version: 5.0 + EDR - Waterproof Rating: IPX6 - Country of Manufacture: China I opened the box and used them a few times, but I'm selling them because I don't have a chance to use them anymore. The box has several scratches (see photos from the third image), but the main unit (earphones, charging case) is in good condition. Spare earbud tips are included, so you can replace them.
