I don't know if this headset fits all your criteria, but I myself have been using the Logitech 433 since 2018 and am pretty happy with it.
It is closed back, has a detachable microphone and cable and therefore comes with a 2m cable for using with your PC and a shorter 1m cable to take it outside.
You can connect it via 3,5mm headphone jack or plug it into a USB-C [Edit] USB-A adapter.
Over the years it developed some "quirks", like a loose contact that occasionally causes noise to deafen both me and all the poor participants in a voice call with me. Usually getting a replacement cable fixed the issue. Maybe I treated it poorly, maybe the cables aren't build to last. I honestly couldn't tell. xD
Not sure if it's bass boosted, tbh it might be.

It's not boomy but rich, as I believe @Cocococo said correctly it has boosted upper bass.  but it's not noticeable and gives a pleasant sound signature
