I have the same headphones. I went to Batteries Plus and purchased a similar battery, NUON, NU67, 3.6v 320mAh. The original battery is 3.6v 280mAh. The 320mAh holds the charge longer. You must swap the connector from the old battery to the new battery in order tomake it work. This can be done two ways, carefully removing the connector or cut, splice, solder and insulate the battery leads. Removing the connectors is tricky because the leads lock into place when inserted into the connectors. Good Luck.
