This is a JBL SOUNDGEAR SENSE. I purchased it at the end of April 2024 (the receipt is included in the last photo), but it didn't quite fit me (I have larger ears and wear glasses), and it felt like it was going to fall out, so I'm selling it. *Product Condition* I've used it almost daily indoors since I bought it. Operation has been confirmed. All accessories, such as the instruction manual and cable, are included, and it has a manufacturer's warranty until April 22, 2025. *Packaging and Shipping* I will ship it in the same outer box it arrived in. It's been less than two months since I purchased it, but it is a used item, so please understand this before purchasing. I cannot accept claims or returns, so please ask any questions you may have, no matter how small, before purchasing.
