The MZ-RH10 is a Hi-MD Walkman offered in black, silver, blue and orange. Black models feature black transport buttons and jog wheel, while other colors feature silver transport buttons and jog wheel. All models feature a silver accent on the edge and battery door.

Its sister model, the MZ-M100, was sold as a field recorder (packaged with Sony's ECM-DS70P stereo microphone) and boasting Macintosh support for Linear PCM uploading. The MZ-M100 features black transport buttons and jog wheel, and a black accent on the edge and battery door.

The two models are otherwise largely identical other than their external appearance and included items, they all share a large OLED display, and support for running off external AA battery power (with the included EBP-RH10 battery case).

Both models appear to have been released worldwide, however, mainly Japanese examples have appeared for sale recently on the Internet. The Japanese models include support for a charging dock.

Note: The OLED screen is known to go bad rather quickly, and there are no known replacements. In fact, I haven't seen any with an actually working screen in a few years. It can still be used with a remote, though some settings may be difficult to change.

Disassembly tips

  • There are two hidden screws behind the battery cover and another one under the eject slider that need to be removed when opening the unit up as well as the more obvious ones.
  • There is a cover/slider that can be moved to cover either the micro USB port or DC jack on the side. Removing the casing is easier with the slider covering the DC jack and exposing the USB port. This is probably the most delicate part of the rear casing.
  • The rear casing is easily cracked if not removed carefully. With the screws and battery cover removed, start easing it off around the battery cover, where the eject button is and then where the contacts for the battery caddy and USB port reside. Once those 3 sides are free, unhook it from over the headphone/remote, line in and mic jacks.



Other detail photos. My unit…has seen better days. Currently non-functional stand-alone.

This unit was purchased on eBay as a junk item. The screen is dead, but otherwise this is in good shape cosmetically and functionally.
