T7-KY1 wireless earphones with a digital display charging case and red LED indicator. These are 3coins earphones, but the bass is great, and the sound quality is so good that you'd think they were expensive wireless earphones. - Model: T7-KYK - Battery Capacity: 300mAh - Display: Digital display - Charging Case: Transparent case - LED Indicator: Red LED I lost the left earphone. Only the right one is available. It's in good condition and still works without any problems. Thank you for looking.
