I recently purchased these but am selling them because I bought another pair of earphones. They are the Sport X20 wireless earphones, featuring IP68 water resistance and adaptive ANC. I used them during weight training, and I was impressed by the sound quality and noise cancellation. They never fell out once. - Model Name: Sport X20 - Water Resistance: IP68 - Features: Adaptive ANC - Charging Case Color: Black - Design Features: FlexFit ear hooks Thank you for looking.
