The following is a partial list of Sony Walkman products which includes products of various formats under the brand. Up to March 2010 Sony built 400 million Walkmans (of which slightly over half - 200.02 million - were original cassette Walkmans) worldwide.walkman-archive.com, Gallery Sony, retrieved 31 May 2020.

Walkman (original cassette tape) The original Sony Walkman TPS-L2 was introduced on July 1, 1979. Through the 1980s and 1990s, Sony created many versions and variations in the cassette tape Walkman line such as the DD series and WM series.

Below is an incomplete list of cassette tape based Walkman models.

GV-D1000 MiniDV Video Walkman GV-D900E PAL Mini DV

DAT Walkman

Portable Digital Audio Tape (DAT) players called DAT Walkman were made. The first model, TCD-D3, was released in 1990. The final model, TCD-D100, was discontinued in Japan in 2005.

MiniDisc Walkman

The first MiniDisc Walkmans ("MD WALKMAN"), MZ-1 (recorder/player) and MZ-2P (player), were released in 1992. Until end of 1998 4.6 million units of the MD Walkman were built. Production of the final MiniDisc Walkman, MZ-RH1 (Hi-MD), stopped in September 2011. List of models:

supported MDLP 2000: MZ-E500, MZ-E700, MZ-E900, MZ-R900 2001: MZ-E909, MZ-R909 2002: MZ-E10 Net-MD 2001: MZ-N1 2002: MZ-N10 2003: MZ-N910 Hi-MD 2004: MZ-NH1, MZ-NH3D, MZ-EH1 2005: MZ-DH10P, MZ-RH910, MZ-RH10 2006: MZ-RH1

R Series The MZ-R2 was one of the earliest MD Walkman products, released in December 1993. It was followed by the MZ-R3.

E Series The MZ-E series models are all exclusively players (i.e. they do not record).

The MZ-E50 was the smallest and lightest MiniDisc player when released in late 1996.

B Series The first B model was the MZ-B3 recorder from 1995. There were later also the MZ-B50 recorder, released October 2000, the MZ-B100, and the MZ-B10.

N Series

Sony expanded MiniDisc's possibilities with the introduction of NetMD (NetworkMD). These allowed the use of a PC to convert music from CDs or MP3s into ATRAC3 format, and use a USB cable to transfer the music to the MiniDisc at a much faster rate than was possible when using a line-in cable.

The MZ-N10 was released in 2002. It was Sony's '10th Anniversary' product, released 10 years after the introduction of the MiniDisc format in 1992. The case was made from a magnesium alloy, and the unit featured a built-in lithium-ion battery which provided 24 hours of battery life. The MZ-N10 allowed music to be transferred from a PC at up to 64 times actual playback speed, not including the time required for audio re-encoding. It was also the first MD Walkman to incorporate the ATRAC DSP TYPE S codec, and is today (2006) the lightest recording MD Walkman ever produced. The accompanying 10th anniversary playback-only MiniDisc Walkman, the MZ-E10, was also released. It is the lightest MD Walkman ever produced, weighing 55 g (including built-in rechargeable battery) with a thickness of 9.9 mm.

Hi-MD compatible players In 2004, Sony introduced the Hi-MD format. Hi-MD Walkmans use 1 GB Hi-MD discs in the same form-factor as regular MiniDiscs, and allow 1 GB of files and/or audio to be stored per disc. They also accept regular MiniDiscs, which can be initialized in Hi-MD mode for 305 MB capacity per disc (with the added ability to store audio and data, like Hi-MD discs).

Unlike NetMD, Hi-MD Walkmans allow two-way digital transfers to and from PCs virtually unrestricted. Hi-MD also allows the option to record and transfer audio in lossless linear PCM on standard MiniDiscs and Hi-MD discs. This offers sound quality equal to CD (as opposed to lossy ATRAC codecs used on standard MiniDisc/ NetMD).

Hi-MD Walkmans introduced from 2005 onwards allowed direct playback of MP3s without the need to transcode the MP3s to ATRAC format. However, SonicStage is required for transfer onto the disc itself. Playable audio cannot be transferred to the devices without SonicStage.

DVD Walkman (formerly DVD Discman) In 1998 portable DVD players called DVD Discman were released. New models from 2001 were rebranded as "DVD Walkman".

Walkman (formerly Network Walkman) Released in 1999, these would be the first "memory type" Walkman, which remain the only current product type still in production. Initially from 2000 these products were collectively called Network Walkman to distinguish from other types of Walkman such as the cassette one. By 2006 the branded name for memory type Walkman became solely Walkman, which continues to this day.

As Sony did not initially support the MP3 format, which was already the dominant format among its industry competitors, Sony's players were not officially called "MP3 players". At the start, the Memory Stick flash players were officially called (albeit not necessarily marketed as) "Portable Memory Stick Audio Players"; embedded flash players were officially called "Portable IC Audio Players"; hard disk players were given the official moniker of "Portable Hard Disk Audio Players". From 2005, all digital memory devices of the Walkman line were simply called "Digital Audio Players" or, as video capabilities became more common, "Digital Media Players".

From 2007 to 2015, Walkman players for export markets had a NWZ- product code prefix instead of NW-. The main difference was the removal of compatibility with the ATRAC audio codec.

Memory Stick Walkman NW-MS7

The NW-MS7 "Memory Stick Walkman" was introduced on September 22, 1999 during a Walkman 20th anniversary event as Sony's first foray into the portable solid state music player industry. The player was very small and light (69 g) with a "stylish" design. It shipped with a white 64 MB MagicGate Memory Stick and built-in battery, selling it alongside the later NW-E3 (64 MB built-in and using two AAA batteries for 4 to 5 hours playback duration). The player could only play ATRAC formatted files, Sony's proprietary format, so was not technically an "MP3 player". The user needed to transfer songs via USB with bundled software OpenMG Jukebox (only works with Windows 98 software, later known as SonicStage). Any files not in the ATRAC format (i.e. MP3s) needed to be converted before they could be transferred and played. Popular software players at the time, such as Winamp, did not support the ATRAC format, leading to users needing to store both MP3 and ATRAC copies of songs on their computers. Additionally, only new MagicGate Memory Sticks were supported.

Sony also advertised the player as having "robust" copyright protection by adhering to standards including Secure Digital Music Initiative. It would only play protected legal music downloads.

It was released on December 21, 1999 in Japan with a price of 45,000 JPY, followed by January 2000 in the United States for $399. It was the first and only memory type Walkman to use the classic "WALKMAN" logo, with the NW-MS7 branded as MS WALKMAN. In 2000 the current "W." logo was created to fit more easily on the increasingly shrinking size of devices, and the Walkman brand was unified.

NW-MS9/MS10/MS11

The Memory Stick-based Walkman was updated with the NW-MS9 and NW-MS11, with it now coming under the umbrella Network Walkman naming. These players came bundled with either 64 MB/128 MB MagicGate Memory Sticks and used a gumstick type battery. Software continued to use OpenMG. The NW-MS9 now had a thin metal body and had 64 MB of internal memory and was priced $330. Release in Japan of the MS9 was December 2000 and April 2001 in Europe. In Canada it was released in August 2001.

NW-MS11 was released in Japan in October 2001 and came with a 128 MB Memory Stick.

NW-MS70D/MS90D The last Memory Stick-based Network Walkmans were released in 2002, although these new models also included internally embedded flash memory.

Model NW-MS70D had 256 MB of built-in flash memory. It could also be expanded by its MagicGate Memory Stick Duo port. However, at the time, the Memory Stick PRO Duo had not yet been released, so the maximum capacity remained at 384 MB with the additional memory stick. Another criticism was that it was incredibly expensive, priced equivalent to a 15 GB iPod. It also mandated the use of notoriously buggy software (SonicStage) and could only play music encoded as ATRAC3, ATRAC3Plus, or WAV. It was, however, the smallest digital audio player available at the time, termed "ultra compact" by Sony. It was also solidly built with an aluminium shell and a titanium finish. It had a 44-hour battery life.

Despite a heavy marketing campaign, sales of the memory stick models were limited. The devices were much more expensive than competing iRiver and Mpio players that did not require SonicStage or ATRAC transcoding. Inexpensive Zen and Muvo players from Creative Labs further hindered Sony's sales.
