The Sony WM-EX641 Walkman portable cassette player features a wired remote control. It was manufactured in Japan and released around 1999 to the early 2000s. The player is entirely black, with the brand and model number printed in white on the front. It features automatic flip-to-play, Dolby B noise cancellation, and subwoofer enhancement. The battery compartment on the side of the device uses a single AA battery. For those looking for a fully functional cassette player, this might be a suitable option.
