The headphones' batteries ceased to hold a charge after two years of use. They don't accept services for repairs, but I did find one whose issue pricing is $4500. The right one takes 1.5 hours, the left one 50 minutes. I believe that the batteries decayed so quickly due to self-discharge because a fully charged case with headphones discharges in a week. Firmware updates have not corrected the self-discharge problem.
