I've been using these for about six months, and I'm selling them because I'm upgrading. The accessories are as shown in the photos. These are wireless earphones with Bluetooth 5.4 and ANC (Active Noise Cancellation). I imported them from Aliexpress, so their technical compliance certification (技適) status is unknown. I'm also including the KZ-Vader balanced version. Please consider purchasing if you understand that these are used items. - Model: KZ-AN01 - Bluetooth Version: 5.4 - Bluetooth Range: 15m - Battery Life: 8 hours - Case Battery Capacity: 400mAh - ANC Function: Yes - Codec: SBC/AAC/LDAC
