Bose QuietComfort Headphones: price, specs & release date

Fetched the official Bose US product page (bose.com QC-HEADPHONEARN); its Technical Specifications table and FAQ confirmed verbatim "Noise Cancelling: Yes" / "Noise Control Type: Active Noise Cancelling" (anc=true), "Battery Life: 24 hours" with FAQ "provides up to 24 hours of audio playback with noise cancelling turned on" (battery (hr)=24, ANC-on figure), in-box "3.5 mm to 2.5 mm audio cable" plus "audio cable with in-line mic for situations without Bluetooth" and "plug into bold sound, even without a Bluetooth connection" (wired option=true), headphone weight "0.520 lb" (~236 g), and price "Price is: $359.00" — but it lists only "Wireless Connectivity: Bluetooth" with no version number and states no driver size or codec list. Corroboration: headphonecheck.com's review of this exact 2023 model stated verbatim "Bluetooth version 5.1" / "BT version: 5.1" (bluetooth="5.1"), "the SBC and AAC codecs" / "BT codecs: SBC, AAC" (codecs="SBC, AAC"), "Weight without cable 240 g" (weight (g)=240, matching the catalog's without-cable convention and consistent with Bose's ~236 g headphone figure), "The battery life has improved by two hours to 24 hours", and repeatedly "new edition for 2023 / 2023 model / 2023 version" (release="2023", year only — no month stated on either page). driver (mm) is left blank: neither fetched page states a driver diameter (headphonecheck lists only "Transducer principle dynamic"). Model confirmed exactly as the base "Bose QuietComfort Headphones" (QC-HEADPHONEARN) — the product page's own FAQ contrasts it against the QuietComfort 45 and QuietComfort Ultra, so no sibling/variant ambiguity. headphonecheck.com (the catalog's established review corroboration source) serves as corroboration for the specs the Bose page omits. 7 of 8 spec keys recorded and price sourced verbatim, so publish=true.
