I listen to the Genealogy Guys podcast which has pretty poor (in my opinion) audio quality. Given they are so notable and have sponsorship from some big companies, it is surprising to me that they have not invested in better quality audio equipment! However the content of their podcast is excellent which is why I continue to listen.
The Genealogy Guys have also recently started a monthly podcast where they interview a well known genealogist for about an hour - that podcast is excellent and highly recommended.
I also listen to Lisa Louise Cooke, she has some great podcast materials, I really like how each month her free podcast includes a segment focused on DNA, I learn a lot from her and her guests.
