STRUIK Bluetooth 5 wireless earphones. I used these about once a week for 2-3 months, but I'm selling them because I bought new earphones. The main unit has been cleaned. The spare silicone ear tips are unused. I couldn't confirm any functional problems, but there may be some battery drain due to aging. Please purchase only if you understand this. Includes: Left and right earphones Charging battery case Replacement ear tips Other features: Noise canceling
