Source: helpguide.sony.net (verified 2026-07-11) · corroborated by cined.com. Sony's official Help Guide specifications page for the ECM-W3/ECM-W3S confirmed the dual-transmitter ECM-W3 specs verbatim: Bluetooth 5.3 (LC3plus) 2.4 GHz link, "Up to 150 m" working range, "6 hours" microphone runtime, "120 dB SPL" maximum input, "17 g" transmitter mass, receiver "Ø3.5 mm mini jack (stereo)" plus USB Type-C outputs, and 48 kHz/16-bit or 24-bit audio (no 32-bit float). CineD's dated launch article (Oct 2, 2023) confirmed model identity — distinguishing the two-mic ECM-W3 at $469 from the single-mic ECM-W3S at $349 — plus the onboard "Noise Cancellation" switch, and that the charging case's added runtime was left "unspecified" (so total-system battery hours is null). Price ($469) is the ECM-W3 dual-kit launch MSRP quoted verbatim by CineD.
