SONY WFXB700 / BZ Wireless Earbuds Junk Bluetooth may disconnect during use. It requires putting them back in the case and reconnecting. There are some scratches on the case and the main units. I would be grateful if you could use them as junk items. The charging case, earbud units, and replacement ear tips are included in the box. A charging cable is not included. They can be used, but as described above. Those who understand that these are junk items, please consider purchasing.
