Wireless earbuds with noise-canceling and up to 28 hours of battery life. - Brand: soundcore - Model Name: Liberty 4 - Color: Black - Features: Noise-canceling - Included: Charging case, ear tips - Battery Life: Up to 28 hours I've been using these for about six months. I've had a silicone case on them since I bought them, so the case itself has no scratches. Thank you for looking.
