Keyboards and headphones are nerd black holes . I'm also pro good keyboard but it may be difficult to find at this stage. My rec is that if you aren't picky, use whatever you have or borrow it from work if possible. My employer basically said if you can carry it and need it - please take it home. If you share WFH space with others then for their sanity, perhaps use the quieter mechanical keyboard and/or order more noise cancelling headphones.

Headphones - Bose QC over-ears tend to work with mic & audio for zoom PC/mac calls via bluetooth. Sony WH-1000MX3's don't seem to allow enough bandwidth for voice when connected with my macbook (perhaps a different supported bluetooth codec ?) and/or the mic has gotten worse since I bought it. The mic doesn't work when it is plugged in with the headphone jack (as per spec). My in-ear headphones with mic will tend to fall out if I don't insert them properly like ear plugs and/or when I'm talking for longer durations. I should have brought my over-ear mono headset home from work but would need another usb-c w/ PD dongle to support that. I'll probably get some cheap ear add on ear hooks for ear pods and/or V-Moda Boompro to add to the Sony's. Zoom also lets you call into meetings via phone.
