Sony MZ-RH10 & MZ-M100

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.
