Why Replace the Battery?

Rechargeable headphone batteries naturally lose capacity over time. If your headphones:

• No longer hold a charge

• Run for only a short time

• Shut off unexpectedly

• Require frequent recharging

• Won't power on even after charging

a replacement battery can help restore the cordless functionality of your headphones without replacing the entire headphone system.
