Thank you for viewing. I am selling the SONY WF-1000XM4 (Platinum Silver) true wireless earbuds as junk. • Right earbud: Power turns off 1-2 minutes after starting use • Left earbud: Battery runs out in about 30 minutes • Charging case: Operation confirmed • Left/Right identification: L (Left), R (Right) Due to battery failure, normal use is difficult. Please consider this for repair or parts. Only those who agree with the condition are welcome to purchase.
