What our readings say: Has been $17.08 within 13 days.
AliExpress prices this listing at 119.00 CNY. The $17.88 above is that figure converted by their affiliate API. AliExpress’s own site converts at a slightly different rate, so it may show a few percent less — the CNY number is the one neither of us converted.
Seller lists it at $35.75 — a claimed saving of $17.87. AliExpress does not verify that figure, and 38.4% of the listings we track make a claim in the same 50-59% range, so on its own it means very little.

Z55H Replacement Lithium Battery For Sony WF-1000XM4 Wireless Bluetooth TWS Earbuds Spare Cell — listed under Electronics. Full specifications are on the AliExpress product page.
8 products in Electronics close enough to compare on price — 7 are cheaper than this one.
We track 6,875 products in Electronics. At $17.88, it sits above the middle of that category, which is $6.10 — a range covering very different kinds of product, so read it as placing the price, not judging it.
The seller claims 50% off. So do 33,510 other products we track — 38.4% of our whole catalogue claims a discount in the 50-59% band. At that frequency the figure is a listing convention rather than a signal. Either way AliExpress does not check strike-through prices, which is why we record our own instead of repeating theirs.
We have recorded this product’s price on 13 separate days since 2026-08-09, and it has moved 10 times in that window. This history was recorded over time, not reconstructed after the fact — the longer we track a listing, the stronger the evidence becomes.
If you buy through our link, AliExpress pays us 7.0% of the sale. It costs you nothing extra, and we publish the rate so you can judge our incentive for yourself.
All under $17.88 with at least 100 reported orders.
