Sony Hi-MD Walkman MZ-RH1
It is the last and most capable Sony portable MiniDisc recorder: it plays and records standard and Hi-MD discs and is the one unit that can digitally copy recordings from old standard MDs to a computer over USB.
Not for: Anyone who wants a new product with a warranty, or a cheap way to play a few old discs. MiniDisc players have been out of production for years, so every unit is used or old stock, and the MZ-RH1 sells at a collector premium.

Sony Walkman MZ-N707
MiniDisc playback, convenient AA-battery power, and recording capability make it a practical used choice for an existing disc collection.
Not for: Anyone wanting Bluetooth, streaming, or a new, currently manufactured player.
Which one fits you
recording with a built-in mic and Hi-MD upload
Sony Hi-MD Walkman MZ-M200
It has a built-in stereo microphone and Hi-MD PCM recording, and it uploads recordings over USB, which makes it a good field recorder.
Not for: People who mainly want to play an existing library of standard MDs and need the RH1's legacy-disc upload.
slim playback only
Sony MZ-E series MZ-E10
It is an ultra-thin playback-only Walkman for listening to existing discs on the go.
Not for: Anyone who needs to record or transfer audio, or who wants a player that is easy to source with a working battery.
budget NetMD transfer from a computer
Sony Net MD Walkman (line)
Sony's many Net MD recorders are common and affordable, and they accept music transfers from a computer over USB.
Not for: Anyone who wants to copy recordings off a disc to a computer, since standard Net MD units mostly transfer one way.

Brands that matter
- Sony: Invented the format and made the widest, best-supported range of players, from the early MZ models through Hi-MD.
- Sharp: A major MD maker with well-regarded portable recorders, a solid alternative on the used market.
- Panasonic: Made compact portable MD players and recorders, which are less common today.
- Kenwood: Made a smaller number of portable MD units, mostly playback-oriented.
What to avoid
- Listings marked untested or sold as is, unless you can repair the unit yourself.
- Units with a green or corroded battery compartment.
- Units sold without their proprietary charger, dock or remote when you need them.
- Assuming a Net MD unit can copy your old recordings back to a computer.
Questions
Can I still buy blank MiniDiscs?
Sony has ended MD media production, so blanks come from remaining stock and used discs. Standard MDs can be reused many times.
Will a Hi-MD player play my old standard MDs?
Yes. Hi-MD units play and record standard MDs, but discs formatted as Hi-MD will not play on older non-Hi-MD units.
