Which Sony Walkman is this? The model codes, decoded

Sony has put the Walkman name on five different kinds of machine, and the prefix on the model plate tells you which. TPS-L2 and WM- are cassette. D- is CD (sold as Discman first). MZ- is MiniDisc. NW- and NWZ- are digital files. If the code starts with NW, it has never played a tape in its life.

Last verified 1 September 2026 against 120 Walkman-titled listings from 18 US advertisers in the CJ product feed.

Sony Signature Series NW-WM1ZM2 Walkman with a gold-coloured chassis and a colour touchscreen showing album art — The NW-WM1ZM2, asking $3,699.99 at Sony on 1 September 2026. NW means digital files. This is the most expensive object in our entire pull and it cannot play a cassette.

Read the prefix first, the number second

Every Walkman argument on the internet is really an argument about which Walkman. The prefix settles it in one glance, and it has been consistent since 1979.

Prefix	What it plays	In production	Example
TPS-L2	Compact cassette	1979 — the first one	TPS-L2, Japan 1 July 1979
WM-	Compact cassette	1981–2010	WM-2 (1981), WM-20 (1983), WM-FX290W (2004)
D- / D-EJ	Compact disc	1984–c.2010	Sold as Discman first, CD Walkman later
MZ-	MiniDisc	1992–c.2011	MD Walkman; never more than a niche
NW- / NWZ-	Digital files on internal storage	1999–present	NW-E394, NW-A series, NW-WM1ZM2

Two extra tells worth knowing. A Walkman with SRF- in the code is a radio, not a tape player — Sony started applying the brand to transistor radios with the SRF-40 in 1980. And an S in the middle of a cassette code, as in WM-SXF33, means the sports line: the rubber-armoured ones people remember from a gym bag.

How to date a cassette Walkman without a receipt

Metal case, blue and silver, two headphone jacks and an orange button. That is the TPS-L2, the original, on sale in Japan from 1 July 1979 at about ¥33,000 and in the United States from June 1980. In the first markets it was sold as the Soundabout in the US, Freestyle in Sweden and Stowaway in the UK; a machine carrying one of those names predates the worldwide switch to the Walkman name in the early 1980s.
Soft-touch buttons and a body noticeably smaller than the first one. WM-2, 1981.
A radio built in. Not before 1982 — the WM-F1 was the first.
A Dolby noise-reduction switch and auto-reverse. Also 1982 at the earliest.
A body about the size of the cassette itself, with a telescopic case. WM-20, 1983. This is the shape that fixed the Walkman in everyone’s memory.

Honest empty: none of these tells authenticates anything. Sony made roughly 220 million cassette Walkman units before ending production in 2010, so a genuine 1980s unit is common rather than rare, and a machine’s value sits almost entirely in whether the belt and the head still work — something no listing photograph can show you.

What is actually on sale under this name today

We pulled every Walkman-titled listing from US advertisers on the affiliate network, read all 120 of them individually, and found nine that are Walkman hardware. Seven are players. Two are replacement batteries.

Model	Prefix means	Advertiser	Ask
NW-WM1ZM2 Signature Series	digital files	Sony	$3,699.99
NW-WM1ZM2 Signature Series	digital files	Macy’s	$3,698.00
NW-WM1AM2 Hi-Res 128GB	digital files	Sony	$1,399.99
NW-WS623 waterproof, Bluetooth	digital files	Sony	$149.99
NW-E394 8GB	digital files	Sony	$74.99
NW-E394 8GB	digital files	Abt Electronics	$73.00
NW-E394/R 8GB, red	digital files	Beach Trading Co.	$73.00

Every single one begins with NW. The cassette Walkman is not sold new anywhere in this market, which is what you would expect: the last cassette model offered in the United States was the WM-FX290W, released in 2004, and Japanese production stopped in 2010.

Sony NW-E394 Walkman digital music player in red with wired earbuds, showing the screen and transport buttons — NW-E394, $74.99 at Sony. The E series is the cheap end and has been since the mid-2000s.

Sony NW-WS623 waterproof wireless Walkman, a grey horseshoe-shaped headphone with the player built into the band — NW-WS623, $149.99. The WS series puts the whole player in the headband and is rated for swimming.

The trap: 43 peer-to-peer listings, zero machines

This is the finding we did not expect and it is the one worth carrying away. Of the 120 Walkman-titled listings, 43 come from peer-to-peer marketplaces — and not one of them is a Walkman. They are t-shirts, a Tony Hawk CD case, a Sony Tape promotional cap, a JanSport fanny pack, swim trunks, a windbreaker and a printed face mask. The word "Walkman" in a resale title in 2026 is far more likely to describe a graphic printed on cotton than a machine with a tape door.

Our own view, since someone has to say it: the NW-WM1ZM2 at $3,699.99 is a genuinely serious audio player and a genuinely absurd thing to buy because you liked your Walkman in 1989. Those are different purchases wearing the same six letters. If nostalgia is the motive, the object you want has WM- on it and costs a fraction as much on a marketplace this feed does not reach.

Frequently asked about Walkman model codes

How do I tell if my Walkman plays cassettes?

Look at the model code. TPS-L2 and anything starting with WM- is a cassette machine. D- is CD, MZ- is MiniDisc, and NW- or NWZ- plays digital files only. The prefix has been consistent since 1979.

What was the first Walkman model?

The TPS-L2, a blue-and-silver metal-cased personal stereo, on sale in Japan from 1 July 1979 at about 33,000 yen and in the United States from June 1980. Sony expected 5,000 units a month and sold over 30,000 in two months.

When did Sony stop making cassette Walkmans?

Production ended in 2010. The last cassette model sold in the United States was the WM-FX290W, first released in 2004. Roughly 220 million cassette-based units were made in total.

Is a new Sony Walkman still sold in 2026?

Yes, but only digital ones. Four models appear in live US affiliate feeds on 1 September 2026: the NW-E394 at $73.00 to $74.99, the NW-WS623 at $149.99, the NW-WM1AM2 at $1,399.99 and the NW-WM1ZM2 at $3,698.00 to $3,699.99.

Why is my Walkman called a Soundabout?

Because it is early. Sony launched the TPS-L2 under different names by market: Soundabout in the United States, Freestyle in Sweden and Stowaway in the United Kingdom. The single worldwide Walkman name came in the early 1980s.
