IPX4 Waterproof Bluetooth Wireless Earphones Open Ear Headphones - Model Name: PT-OEE-BK - Color: Black - Waterproof Rating: IPX4 - Bluetooth Version: Bluetooth - AAC Support: Yes - Continuous Playback Time: 4 hours Thank you for viewing. I purchased these at Don Quijote in June, but they didn't suit me, so I'm selling them. Warranty card and receipt for warranty attached. I tried them on once, but they have been stored in the box since then. Although they are new, I have marked them as "slightly scratched or dirty" because the cover for the charging part has come off. (Photos 7 and 8) I tried several times to put it back in, but I couldn't, so I'm selling them as is. The box also has some scratches from opening. I will ship as quickly as possible, but it may be delayed due to work. Thank you for your understanding. Thank you. #WirelessEarphones
