Replacement Battery for Sony Headphones

This lithium-polymer cell replaces the original pack in Sony WH-1000XM3, WH-1000XM4 and WH-CH710N/B headphones. It delivers 1000 mAh at 3.7 V and matches the 42.06 x 39.50 x 6.80 mm footprint of the factory unit. A decoded chip reports capacity to the headset exactly like the OEM component.

Upgrade From Depleted Original Cells

The battery restores full runtime when the original pack no longer holds a charge after years of daily use. The jump is worth it when noise-cancelling time drops below a useful level or the headset shuts down unexpectedly. It fits the same compartment and connects to the existing connector without modification.

Straightforward Swap With Connector Care

Installation requires opening the earcup, unplugging the old pack and seating the new connector firmly. The most common issue is a partially seated connector that causes intermittent power or no power at all. A complete charge-discharge cycle or two brings the pack to its rated capacity.

Questions about this item

Will the 42.06 x 39.50 x 6.80 mm dimensions fit the battery compartment of my Sony WH-1000XM4?

Yes, the pack measures 42.06 x 39.50 x 6.80 mm and is listed as compatible with the WH-1000XM4, WH-1000XM3 and WH-CH710N/B models.

What is the critical step when connecting the replacement cell inside the headset?

Ensure the connector is fully seated and properly aligned before closing the earcup; a loose connection will prevent the headset from powering on.

How many charge cycles until the 1000 mAh capacity stabilises at its rated level?

The manufacturer notes that a new cell reaches its best performance after 2 or 3 complete charge and discharge cycles.
