Replacement Battery for Sony Headphones

This Estry lithium cell is a direct replacement for the original battery in compatible Sony headphone models. It delivers a capacity of 1000mAh at 3.7V and matches the factory dimensions of 40.5 x 39.5 x 6.8mm. The pack includes built-in protection against overcharge, over-discharge, over-voltage and short circuits.

For Owners of Specific Sony Models

This cell suits owners of the WH-1000xM3, WH-CH710N/B, WH-XB900, WH-XB900N or WH-1000XM4 who need to restore original runtime. It is not for users whose headphones use a different battery part number or form factor. Buyers who cannot confirm their model against the listed part numbers should look elsewhere.

1000mAh Capacity Restores Stock Runtime

The 1000mAh rating determines whether this cell matches the energy storage of the original battery. Verify that your current battery carries part number 1588-0911, SM-03, SP 624038 or LIS1662HNPC before ordering.

Questions about this item

How do I install the Estry WH-1000xM3 battery and what step do people often miss?

Open the earcup, disconnect the original 1588-0911 pack, connect the new 1000mAh 3.7V cell matching the polarity, then reassemble; many forget to verify the connector clicks fully.

What maintenance or replacement will this 1000mAh lithium pack need later?

No scheduled upkeep is required; when runtime falls well below the original 3.7Wh level the pack should be swapped for a fresh unit.

What limit appears first during sustained use of this 3.7V replacement?

The 1000mAh capacity sets the runtime ceiling; the built-in protection stops output if voltage drops too low or current spikes.
