I purchased this item new and unopened on Mercari in October of this year. I only listened to it once, and it is in extremely good condition with no noticeable scratches or stains. There were no problems with the operation or connection. All accessories (2.4GHz dongle, USB-A adapter, ear tips, USB cable, and guides) are included. *Instant purchase is welcome. No price negotiations. The AKG N5 wireless earbuds feature 40 hours of battery life and noise-canceling, and offer a comfortable in-ear fit. - Brand: AKG - Model Name: N5 Hybrid - Noise-canceling: Yes - Battery Life: 40 hours (10 hours on the main unit) - Charging Case: Yes - Design: In-ear - Color: Black Gaming Earphones Hi-Res Bluetooth
