Thank you for viewing. This is a Bluetooth headset, the G9. I purchased it two weeks ago and used it three times. I'm selling it because I wasn't satisfied with the noise-canceling function of the microphone outdoors, so I bought a different one. By the way, there are absolutely no problems indoors. I don't think there are any scratches, but please check the photos for the condition. Product Details: - G9 wireless headset with Bluetooth connection, built-in microphone and boom microphone, for both calls and music. - Model: G9 - Bluetooth Type: 5.3 - Microphone Type: Built-in microphone, boom microphone - Usage: Dedicated for calls, music mode Thank you for your consideration. The product is considered used, so please understand that it is non-refundable and non-returnable.
