"With no extra hardware" seems to be a loose interpretation of the paper. Their solution, according to the paper, involves either a COTS earbud that has been taken to pieces and wired into their signal processing box, or a full custom preproduction earbud with 6 extra microphones and an unreleased signal pipeline.
