I am listing these because I purchased new earbuds. I used them for two days of commuting, round trip. Perhaps due to my usage, the right earbud works fine, but the left earbud occasionally has connection interruptions. Please understand this before purchasing. Also, the 7th image says "new and unopened," but it is not new. The images from the 7th image onwards are for product description purposes, so please be aware of this.
