Thank you for viewing. This is the Soundcore Liberty 4 wireless earbuds. I purchased these on April 22nd. I also purchased the Sony WF-1000XM5 and planned to use them interchangeably, but since the WF-1000XM5 lasts for 8 hours, one pair is sufficient. As I rarely use these Soundcore Liberty 4 earbuds, I am selling them in near-new condition. The ear tips are all new, as I used my own memory foam tips. All accessories are included. Get them quickly if you like them. Due to shipping and handling fees, the price is already at its limit, so please refrain from negotiating a discount. Thank you for your understanding. Returns, refunds, and complaints are not accepted. - Brand: soundcore - Model Name: Liberty 4 - Accessories: Charging case, ear tips - Features: Noise canceling, IPX4 water resistance - App Support: Soundcore app - Battery Life: 28 hours
