SONY earphones with charging case and noise-canceling function. - WF-SP700N - Bluetooth connection is not possible. I believe the left side (L) is malfunctioning. Therefore, I haven't been able to test the sound. Charging was possible. - Purchased in Shenzhen, China in 2018. Since it's a China-specific model, the announcements are in Chinese. - Used for about a year, then switched to AirPods. - Used ear tips have been removed, and unused ones will be included. The outer box is included, but it's somewhat dirty, so please consider this before purchasing. I will try to ship as quickly as possible, but it will often be on weekends. Thank you for looking. Other features: Junk, noise canceling
