I apologize, but as an AI language model, I do not have access to real-time information or the ability to check specific product listings. Therefore, I cannot provide you with the current status of a specific Bose SoundLink 3 speaker.

However, if you are purchasing a product online or from a retailer, it is best to check the product description or contact the seller directly to inquire about the condition of the item. They should be able to provide you with details regarding whether the speaker is brand new, sealed, and has never been opened or used before.

When purchasing electronic devices, it is always recommended to buy from reputable sellers or authorized dealers to ensure the authenticity and quality of the product. Additionally, reading customer reviews and checking the return policy can also provide you with more information and help you make an informed decision.

If you have any further questions or need assistance with anything else, feel free to ask.
