Sony’s first Walkman was released in 1970 and cost around 200 dollars.
The latest NW-WM1ZM2 Walkman certainly doesn’t take cassette tapes and comes with a price tag of almost 5 thousand dollars!

Arriving in April, Sony’s new Signature Series Walkman  is a piece of gear for the audiophiles offering an exquisite listening experience in an ultra-premium design.
It features a 99.99% purity Gold-plated Oxygen-Free Copper Chassis and a 5 inch HD touch screen display.

You can also expect to get up to 40 hours of high-resolution playback from this premium walkman.

If 5k is a bit rich for you…there is an 1800 dollar alternative also (NW-WM1AM2).
