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.

** UPDATE ** There is now a 3D printed caddy for a 14500 battery that replicates the LIP8
Disassemble the original battery, taking care of the contacts welded on the old battery, and insert an identical battery, reference CN 14650 3.7 v 1100mAh (normally, there is one a little longer, tenths of mm)
For me it's number 1.
If you are looking for something reliable, you should buy this.
Greetings DonMinidosco, I have them all in the collection, speaking from experience, I still use the devices and more than 10,000 minidiscs.
