WF-1000XM3 Connectivity and sound output have been confirmed. I replaced them because the battery life deteriorated. The "battery low" voice prompt plays after about an hour. Only the case and earphones are included; there are no other accessories like a cable. They show signs of use. The case, in particular, has many scratches. Please consider purchasing only if you understand this. Please note that they will be shipped in a box via the Nekopos service.
