Direct Replacement for Sony Headphones

This Estry battery replaces the original LIS1553 cell in MDR-XB950N1, SRS-X1, SRS-WS1 and WH-CH700N headphones. It matches the factory voltage of 3.7V and capacity of 1000mAh so the device charges and reports capacity exactly as before. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS for safety compliance.

Critical Match: Part Number and Dimensions

The pack measures 47.56 x 32.2 x 6.4 mm and weighs 45.4 g; verify these figures against the old cell before ordering. The connector and pin-out follow the A-2215-026-A specification, so only models listed in the compatibility table will accept it. Buyers with other Sony or third-party headsets cannot use this unit.

Ready-to-Install Cell with Protection Circuit

Each single pack ships as a complete lithium pouch including over-charge, over-discharge, over-voltage and short-circuit protection. No soldering, firmware updates or additional calibration tools are required; simply swap the old module and recharge normally. The bundle contains only the battery — no adhesives, opening tools or manuals are supplied.

Questions about this item

What does the 1000mAh rating mean for daily listening time?

The 1000mAh cell stores 3.7Wh and weighs 45.4g, matching the original capacity so runtime stays the same as when the headphones were new.

Does the 3.7V lithium cell use a standard connector or a proprietary one?

It replaces part numbers LIS1553HNPCS, LIS1553(SY6), LIS1553 and A-2215-026-A, so the original plug and pin-out are retained.

Will the 47.56 x 32.2 x 6.4mm pack fit inside the MDR-XB950N1 without modification?

Yes, those are the exact dimensions of the factory battery, so it slides into the existing compartment with no trimming required.
