SENNHEISER Wireless Earbuds CX 400BT True Wireless - Black ! Junk Item ! Purchased new in 2021 at Yodobashi Camera (receipt available) I used these with pleasure, but the left earbud's battery now only lasts for 20-30 minutes, so I am selling them as a junk item. The charging case works without any problems. The case, earbuds, charging cable, box, and instruction manual are all included. (I have disposed of the replacement ear tips.) Please understand that this is a junk item, and thank you for your understanding.
