Wireless earbuds with Ultra Noise Cancelling, up to 40 hours of battery life. - Brand: soundcore - Model Name: Liberty 4 Pro - Noise Cancelling: Ultra Noise Cancelling 3.5 - Battery Life: Up to 40 hours - Waterproof Rating: IPX4 I've been using these a bit since I bought them a year ago. I used a case, so there are no scratches or stains. However, since I have actually used them, there may be some signs of use. Time Sale: Will be removed if not sold by October 30th. I want to sell these as soon as possible, so this is the final price reduction. Thank you for your consideration. Thank you for looking.
