Recorder with remote controller, and long battery life (for the time of its release, around 7 hours playback).

Available in silver, blue, and orange. The orange model was only sold in Japan.

The remote for Sony's higher end CD Walkmans from the same time period(D-E01/D-EJ01) will function properly with the MZ-R50 including the backlight function.

Some older R50s have a flaw in them that apparently allows you to turn the digital copy protection feature (SCMS) off. By inserting a 24K resistor in to ports 2&4 (counting left to right) of the remote port, you can put the unit in to test mode, and access a menu that lets you turn off SCMS.

The R50 is a nice machine that I have avoided because the LIP8 batteries are harder to find than hen's teeth. The R35 and R30 models are very similar but use the still available LIP12 battery.
