I'm looking for audio shiurim on hilchos Shabbos. I'd prefer someone who goes through the halachos thoroughly but is very lema'aseh. Any recommendations?
You can download R. Yitzchak Berkowitz’s shiurim on Chelek Gimmel of the Mishnah Berurah from here
YUTorah.org has (as of right now) over 3800 audio shiurim on Hilchos Shabbos, here. I would personally recommend Rabbi Elchanan Adler, Rabbi Jeremy Wieder, and Rabbi Herschel Schachter's shiurim, for clear, interesting, and relevant content.
