I prompted for a link/refernce
The high-resolution CT scan revealing the Power Buffer (Supercapacitor) next to the QN3e was conducted on a Sony WF-1000XM6 production model with a flex PCB date code of 2549, indicating it was manufactured in the 49th week of 2025 (early December 2025). This information comes from the iFixit teardown, supported by CT imaging provided by Lumafield, and was published on February 28, 2026, on The Walkman Blog.
The scan was featured in iFixit’s teardown video, where Lumafield’s CT technology revealed internal components not visible through traditional disassembly, including the placement of the supercapacitor.
