This item has been used a few times. There are no issues with its use, but I'm selling it because I have duplicates in the office. It comes with the original box, so I will ship it in the box. The included USB charging cable is also included. It supports multi-connection, allowing pairing with two devices. This is not bone conduction; it uses air vibration near the ear... in other words, it's a regular sound-producing type. You can hear ambient sounds while using it, making it easy to use for those who don't like bone conduction. A Bluetooth 5.3 compatible wireless headset designed for calls, with noise-canceling function. - Brand: Earaku - Model: Wireless Headset - Bluetooth Version: BT 5.3 Thank you for looking.
