I recently purchased the in line  3.5mm headphone to usb-c adaptor so could connect my headphones to the Apple 16 iPhone. However, it does not work. The sound just plays on the phone. Have I purchased the wrong adaptor

That adapter works by taking the 3.5 mm signal, and transfers it to USB-C, and not the other way around (a USB-C signal to 3.5 mm signal). I’m afraid you may have purchased the wrong adapter.

You are using a Sonos adapter for non-Sonos devices? Would the Apple adapter not have been not have been the more obvious choice (and the cheaper option too). See https://www.apple.com/nl/shop/product/mw2q3zm/a/usb%E2%80%91c-naar-mini%E2%80%91jack-adapter
