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. [1]
The original Sony Walkman TPS-L2 was introduced on July 1, 1979. [2] [3]
Through the 1980s and 1990s, Sony created many versions and variations in the cassette tape Walkman line [4] such as the DD series and WM series.
Below is an incomplete list of cassette tape based Walkman models.

Sony branded portable radio receivers with the "FM Walkman" name starting with the SRF-40 in 1980. [7] Various FM, AM and DAB receivers have been made.
Originally launched as Discman in 1984.
ATRAC3, ATRAC3plus, MP3 supported CD Walkman models:
Sony's first brand extension of the Walkman cassette players were portable Video8 cassette recorders with color LCD displays, released 1989. [8] Video Walkman units for the later MiniDV [9] and Digital8 formats were also released.
Portable Digital Audio Tape (DAT) players called DAT Walkman were made. The first model, TCD-D3, was released in 1990. [10] The final model, TCD-D100, was discontinued in Japan in 2005.
The first MiniDisc Walkmans ("MD WALKMAN"), MZ-1 (recorder/player) and MZ-2P (player), were released in 1992. [10] Until end of 1998 4.6 million units of the MD Walkman were built. [11] Production of the final MiniDisc Walkman, MZ-RH1 (Hi-MD), stopped in September 2011. [12] List of models:
The MZ-R2 was one of the earliest MD Walkman products, released in December 1993. It was followed by the MZ-R3. [13]
The MZ-E series models are all exclusively players (i.e. they do not record). [14]
The MZ-E50 was the smallest and lightest MiniDisc player when released in late 1996. [15]
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. [13]

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.
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.
In 1998 portable DVD players called DVD Discman were released. New models from 2001 were rebranded as "DVD 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, [17] [18] 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.
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. [19] The player was very small and light (69 g) with a "stylish" design. [20] 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. [21]
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. [22]
It was released on December 21, 1999 in Japan with a price of 45,000 JPY, [19] followed by January 2000 in the United States for $399. [23] 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. [24]
The Memory Stick-based Walkman was updated with the NW-MS9 and NW-MS11, with it now coming under the umbrella Network Walkman naming. [25] 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. [21] Release in Japan of the MS9 was December 2000 and April 2001 in Europe. [26] [27] In Canada it was released in August 2001. [28]
NW-MS11 was released in Japan in October 2001 and came with a 128 MB Memory Stick. [29]
The last Memory Stick-based Network Walkmans were released in 2002, although these new models also included internally embedded flash memory. [21]
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. [30] 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. [21]
The alternate model, the NW-MS90D, used the same software as NW-MS70D, and had a maximum capacity of 640 MB. It, too, was extremely costly. The most conspicuous difference in the higher-numbered model was its 512 MB built-in memory and its new black shell. Due to its price and limited capacity, it was still largely ignored by the general public and shared the fate of its MS70D sister. Around this time and particularly with these models, the obligatory SonicStage software started to gain a negative reception. [21]
The NW-MS70D, released in Europe in 2003, was the first device using Sony's Virtual Mobile Engine (VME) digital signal processor. [31] [32]
After the MS70D and MS90D, no more Memory Stick type Network Walkmans were released. Future Network Walkmans would only have embedded flash memory or hard disks.
As Sony was losing market relevance amid the widespread success of Apple's iPod range, the company developed for the first time a hard disk-based player. The NW-HD1 was announced on June 30, 2004 dubbed as “the world's smallest portable audio device”. [33] It was smaller and was advertised as having better sound quality than the iPod at the time. The HD1 featured a seven line 1.8 inch LED display and had a 20 GB hard disk. The device was brushed in high quality aluminum. [21]
However, the unit would only play Sony's proprietary format, ATRAC3, whereas other players on the market would play the more open and much more widely used MP3 format without having to be converted to ATRAC3. [21]
Sony did upgrade the HD1 to play MP3s but it still needed SonicStage to transfer the files. The NW-HD1 did not sell as well as Sony had hoped - its asking price of $399 was $100 more than a 20 GB iPod. [21] Its successors, the NW-HD3 and NW-HD5, also failed to make a major dent in the iPod's sales.
The successor to the hard disk-based NW-HD1, the NW-HD3 was a very similar design, but it could now play MP3s natively. [21] It was announced on November 30, 2004. [34]
Sony's next model, the NW-HD5, was announced in April 2005 and released July 2005 [35] and was an updated design from the HD1 / HD3, boasting a simpler control system, an upright handheld format, [36] a user-removable lithium-ion battery, better file format compatibility, a unique "Follow Turn Display" that would automatically align itself based on how the player was held on startup, and updated software. A main feature was its advertised running time of 40 hours, when using low-quality format settings, i.e., 48 kbit/s ATRAC3 files, and no player-based audio enhancements (although the player does include these). Playback of 128 kbit/s MP3s was rated at 30 hours. The player was available in black, silver and red and was not sold in the Canadian market. The NW-HD5 was in direct competition with the 4th generation iPod.
Unfortunately, the NW-HD5 was shipped with a cosmetic design flaw which meant that the buttons developed small visible cracks under their plastic coating. Although this did not affect functionality, many customers complained. Sony United Kingdom Limited allowed owners to send the units back to be re-fitted with slightly raised, crack-resistant buttons.[ citation needed ] Perhaps because of this problem, the NW-HD5 was on the market for a very short time before being pulled in preparation for the next model. The HD5 model was replaced by the A Series (NW-A3000 and NW-A1000) which was also hard disk based. [37]
In January 2006, the NW-HD5 became unavailable as a normal purchase from retail electronics stores and was relegated to online auction sites and used-electronics warehouses as a consumer item.
The A Series was first introduced September 2005 as the top flagship range. Apart from the very first model, all of these are flash memory based players. Over the years, many generations have been produced which continue to this day.
The B Series are ultra portable, entry-level, USB thumb drive style players for the overseas market. The original series, the B100 released in July 2007, was a line of 1 GB (NWD-B103/B103F) and 2 GB (NWD-B105/105F) multifunction MP3 player and voice recording function. It was the first Walkman digital music player to not require SonicStage software - allowing simple drag and drop [38] - but it has been shorn of the ability to play back ATRAC and AAC music files.
The Auto-Transfer option allowed this Walkman to search for all the MP3 files on the PC and then copy these files directly to the Walkman. It also could record CDs directly from a Sony compatible Hifi system via USB connection without any PC (the NWD-B105 also supported WMA files). It also came with a three-line colour display; the voice recorder (MP3) came with bit rates of low (96 kbit/s), mid (128 kbit/s) and high. Models with the built-in FM tuner ("F") had 30 preset stations with a frequency of 87.5–108.0 MHz, with the capability to record and play FM content. The five preset equaliser also had a custom setting option.
In September 2008, its successor the NWZ-B130 series was launched. [39]
The NWZ-B140 was introduced in 2009 featuring the ZAPPIN song search technology [40] which it inherited from the NWZ-W202 player. [41] [42] The NWZ-B150 series was introduced in April 2010 with a 3 line LCD display. [43]
The B160 series was introduced in June 2011. [44] These were followed by B170 series in early 2012, [45] and the current series, B180, in April 2014. The B180 series consists of one 4 GB model, NWZ-B183, and its FM radio variant NWZ-B183F, and has 20 hours of battery life. [46]
The E Series were the very first to be branded Network Walkman in 2000, shortly after the Memory Stick Walkman. They started out as lightweight, portable, gumstick style music players, [47] before turning into budget-oriented candybar style players with colour displays.
The F Series was introduced in 2012 as the replacement of the Z Series. They are portable media players running the Android operating system. The first series, F800, came with Android Ice Cream Sandwich software and was also the first Sony Walkman to support the FLAC format. [48]
The M Series (sole model NW-M505) is a small thumb drive styled player released in Japan in December 2013 for 18,000 yen. [49] The M Series is similar to the E Series except that it is metallic, more expensive, a higher build quality, and features noise cancelation, S-Master MX amp, NFC, Bluetooth with aptX, and a microphone for hands-free phone. [50] In addition changing songs has a twisting "shuttle switch" like the older E400/E500/A600 Series instead of buttons. [51] In Japan it was released in 4 colors topping out at 16 gigabytes (NW-M505). It was released in Europe in late 2014 but only came in black and 8 gigabytes (NWZ-M504). Also release that year in Asia Pacific region. No successors were released in the series.
Sony used the "S2 Sports" brand from other Walkman types for certain fitness-friendly small Network Walkman players. The NW-S4 Sports Network Walkman had a sleek pen shape and a sporty water resistant design and came with an arm strap and 64 megabyte of embedded flash memory. It was released in April 2001 for $200. [52] Later in 2004, the NW-S23 S2 Sports Network Walkman was released with 256 MB internal flash memory. [53] A 128 MB version called NW-S21 was also released. [54]
After 2006, the S Series was repurposed and a wide range of players have been released to this day.
The W series (Wearable) is a wearable music player built into a set of headphones. The original model, the NWZ-W202 was released in 2009 and had 2 GB of internal memory and could play 11 hours of music and can "quick-charge" for three minutes to yield up to 90 minutes of playback. It can play back MP3, AAC (unprotected only), and WMA (subscription included) files. It was the first Walkman with Zappin, a Sony function which allows the user to browse through tracks by playing a snippet of the chorus of each song. [55]
The original model was followed by the W250 series coming in 2 GB (NW-W253) and 4 GB (NW-W254) capacities. In July 2011 the W260 series was introduced which is significantly smaller and lighter. [56]
The W270 series, which is fully waterproof, was released in April 2013. Model NW-W273 has 4 GB internal memory and NW-W274 has 8 GB. [57] Later that year the NW-WH505 and NW-WH303 were introduced, which is a music player combined into a conventional headphone. [58] A higher end variant of the W270, called WS615, features 16 GB of memory, Bluetooth and NFC. [59]
In January 2016, the WS410 series (WS413 and WS414) were announced with a new salt water and dust proof design, and an Ambient Sound feature. [60]
The successor to the WS610 series was released in 2017 as WS620, coming in 16 GB (NW-WS625) and 4 GB (NW-WS623) capacities. Like the WS410, it has improvements in salt water and dust resistance, and it also now has the ability to play FLAC audio files. [61]
Introduced at IFA 2016, the NW-WM1A is a top-end portable media player retailing for €1200, and has 128 GB internal memory. A gold plated edition called NW-WM1Z was also released, retailing for €3300 as part of Sony's Signature Series. Model NW-WM1Z had 256 GB of storage [62] [63]
Models NW-WM1AM2 and NW-WM1ZM2 were introduced in February 2022, with Android replacing Sony's own operating system. It also had a USB-C port replacing the proprietary WM-Port for data connection. [64]
The Sony Walkman X series was a touchscreen audio and video player that was on the market from 2009 to 2010, designed to compete against the iPod Touch. [65] It has a 3-inch (76 mm) OLED touch screen, internet access through Wi-Fi and digital noise-cancelling as well as applications for Slacker and YouTube. It was available in 16 GB and 32 GB versions. No revisions of the X Series were made; it was replaced by the Z Series.
The Z1000, introduced September 2011, was the first Walkman product using the Android operating system. [66]
The ZX Series is a high-end Walkman player. Some of these run on Android software rather than Sony's own operating system.
Between 2005 and 2011, Walkman-branded mobile phones from Sony Ericsson were released. These were mobile phones with extra emphasis on music playback. The first such device was the W800, and the last device that used Walkman branding was Sony Ericsson Live with Walkman.
Walkman-branded mobile phones by Sony Ericsson were first released to Japan in 2006, under partnership with operator KDDI (owned by au). The first model was the W42S 3G phone in 2006 with 1 GB internal memory and expansion with Memory Stick Pro DUO. It was marketed as the "Walkman Phone". [67] It could download music directly to the handset without PC connection using KDDI's web music store. [68] Succeeding models were released called Walkman Phone W52S, Walkman Phone Xmini (W65S), and Walkman Phone Premier3.
After Sony's mobile division ceased to be a joint venture in 2012, Sony Xperia smartphones from 2012 to 2015 came with a Walkman-branded Music application.
Sony has partnered with various companies, brands, and music bands to release special Walkman digital audio players (most exclusive to Japan). Below are some editions:
Walkman, is a brand of portable audio players manufactured and marketed by Japanese company Sony since 1979. The original Walkman started out as a portable cassette player and the brand was later extended to serve most of Sony's portable audio devices; since 2011 it consists exclusively of digital flash memory players. The current flagship product as of 2022 is the WM1ZM2 player.
Adaptive Transform Acoustic Coding (ATRAC) is a family of proprietary audio compression algorithms developed by Sony. MiniDisc was the first commercial product to incorporate ATRAC, in 1992. ATRAC allowed a relatively small disc like MiniDisc to have the same running time as CD while storing audio information with minimal perceptible loss in quality. Improvements to the codec in the form of ATRAC3, ATRAC3plus, and ATRAC Advanced Lossless followed in 1999, 2002, and 2006 respectively.
MiniDisc (MD) is an erasable magneto-optical disc-based data storage format offering a capacity of 60, 74, and later, 80 minutes of digitized audio.
Hi-MD is a magneto-optical disc-based data storage format. It was a further development of the MiniDisc. With its release in later 2004, came the ability to use newly developed, high-capacity 1 gigabyte Hi-MD discs, in the same dimensions as MiniDisc. The last recorder and player was discontinued in 2011. Blank discs stopped production in September 2012.
A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. The data is typically stored on a compact disc (CD), Digital Versatile Disc (DVD), Blu-ray Disc (BD), flash memory, microdrive, SD cards or hard disk drive; most earlier PMPs used physical media, but modern players mostly use flash memory. In contrast, analogue portable audio players play music from non-digital media that use analogue media, such as cassette tapes or vinyl records.
Discman was the name for portable CD players. The first Discman, the Sony D-50 or D-5, was launched in 1984. The Sony brand name for Discman changed to CD Walkman, initially for Japanese lineups launched between October 1997 and March 1998, and then entirely in 2000. Discman and CD Walkman players were discontinued at the beginning of the 2010s when they lost popularity with the general public.
Gapless playback is the uninterrupted playback of consecutive audio tracks, such that relative time distances in the original audio source are preserved over track boundaries on playback. For this to be useful, other artifacts at track boundaries should not be severed either. Gapless playback is common with compact discs, gramophone records, or tapes, but is not always available with other formats that employ compressed digital audio. The absence of gapless playback is a source of annoyance to listeners of music where tracks are meant to segue into each other, such as some classical music, progressive rock, concept albums, electronic music, and live recordings with audience noise between tracks.
SonicStage is a discontinued software product from Sony that is used for managing portable devices when they are plugged into a computer running Microsoft Windows. It comprises a music player and library manager, similar to iTunes, Windows Media Player and RealPlayer. It is used to manage the library of ATRAC and MP3 recordings on a PC.
The W810 is a camera phone produced by Sony Ericsson. It was released in January 2006. It is the successor of the W800.
The Walkman A810 series is a portable media player designed by Sony. It was a flagship model in the Walkman digital player family. The model debuted in Asia in 2007, and then became available in North America. This series updates the previous Walkman A800 of the Walkman A Series, with the same hardware but different on-PC music management program.
SensMe is a proprietary music mood and tempo detection system created by Sony Corporation and employed in numerous Sony branded products, including in some Walkman digital music players, the Media Go application, the PlayStation Portable, and Sony Ericsson and Sony Xperia handsets. It is named Omakase Channel (おまかせチャンネル) in Japan.
The PSX is a Sony digital video recorder with a fully integrated PlayStation 2 home video game console. It was released in Japan on December 13, 2003. Since it was designed to be a general-purpose consumer video device, it was marketed by the main Sony Corporation instead of Sony Computer Entertainment and does not carry the usual PlayStation branding. Initial sales were strong, with the console selling 100,000 units during its first week, thus selling out. Its high cost, however, resulted in poor sales later on, prompting Sony to cancel plans to release the PSX outside Japan. After the price had been lowered in September 2004, sales increased again.
The Walkman X series is a portable music player designed and released by Sony in Japan in 2009. It was marketed as a high-end, internet-enabled model in the Walkman digital player family in 2009. The model debuted in Japan in April 2009, and then became available in North America, Europe, China and also other regions. The Walkman X series was the first Walkman device to feature a touch screen and S-Master digital amplifier technologies.
The Walkman S Series is a line of portable media players designed and developed by Sony, currently marketed in Japan. The S Series made their debut in the fall of 2006 and later were launched in other regions. Although the first generation of models had generic displays, all next generations of players of the S Series had TFT color displays and supported video playback. They were slightly cheaper than the flagship A Series but had more features than the E Series. The S Series was discontinued outside Japan in 2012 and continues solely in the domestic market.
An ATRAC CD is a compressed audio optical disc containing compressed digital audio in the ATRAC3 or ATRAC3plus formats, which are part of Sony's ATRAC family of proprietary audio compression algorithms.
