Thank you for viewing. I am selling this item to declutter. This is a soundproof earmuff that can be used at construction sites, for maintenance work, listening to music, etc. In my subjective opinion, you can barely hear any outside noise. It has been used, and the cover is slightly torn, so I have reinforced it with black tape. There are no problems with its use. Please understand that this is a used item and only purchase if you agree. To prevent any trouble, I do not accept claims or returns. I have never smoked, and I do not have any pets.
