This is a junk item. The connection doesn't work well, and the wiring for the right earbud is visible. The noise canceling on the left earbud works normally, so I don't think it's broken. The case can charge, but the connection didn't work well. I purchased it on 2023/5/28, but the right earbud broke after about a year and has been that way since. I threw away the outer box and replacement ear tips. I cannot take responsibility for this junk item. Returns and exchanges are not accepted. This is a Bose QuietComfort Earbuds II true wireless earbuds. The color is Midnight Blue, and it has noise-canceling function.
