Testing four models trying to be a modern-day Sony Walkman cassette player: the Mulann B-1000 EW, FiiO CP13, We Are Rewind WE-001, and Tomashi F-113. Correction: The Mulann and Tomashi do have a metal flywheel, not plastic as I said -- just not as large or well-balanced of one as in the FiiO or We Are Rewind. And it is possible to adjust the speed of the FiiO without opening the case -- see my follow-up video: https://www.youtube.com/watch?v=zFUp5JRwQUw Time flow: 0:00 Introduction 1:29 The contenders 2:27 Features and sizes 3:51 The mechanism 5:57 Speed and wow & flutter 9:30 Audio quality 13:51 The verdict #RetroTech #cassette #walkman
