Master & Dynamic MW75: price & specs

Master & Dynamic's official product page provided the full tech-spec table: 40mm beryllium drivers, ANC (Adaptive/MAX/All-Day modes with dedicated 4-microphone ANC solution), Bluetooth 5.1 with codecs AAC, aptX Adaptive (up to 24 bit/48kHz) and SBC, "Up to 32 hours of battery life or up to 28 hours with ANC enabled", 338g weight, and both a USB-C-to-3.5mm analog cable and USB-C-to-USB-C hi-res wired connection; it also listed the price as "Sale price $ 599.00". headphonecheck.com's MW75 review corroborated Bluetooth 5.1 (BT version: 5.1), codecs SBC/AAC/aptX Adaptive, 40mm beryllium drivers, up to 28hr with ANC / 32hr without ANC battery, and 32-ohm impedance (its measured 336g without cable / 356g with cable brackets the manufacturer's 338g figure, which is used here). battery (hr)=28 uses the ANC-on rated figure per this catalog's convention; weight (g)=338 uses the manufacturer figure. release date and the release spec are left blank because neither fetched page states an explicit release date (the review is dated only relatively, "4 years ago"). Corroboration uses headphonecheck.com — consistent with this catalog's established use of that source. All recorded spec values, the price, and release date were re-verified verbatim against both fetched pages; nothing required nulling and the model matches exactly (MW75, not a sibling/variant).
