Sony‘s ubiquitous Walkman has come a long way since its initial introduction in Japan in 1979. From its humble beginnings as the TPS-L2 cassette player more than three decades ago, the Walkman now finds itself as a 3-in-1 digital music player/headphones-speaker design courtesy of Sony’s Walkman WH Series. The comfy over-ear designs offer either 30mm or 40mm dome type headphone driver units along with built-in stereo surround sound speakers that can be activated with the flip of a switch. Compatible with both Mac and Windows, the built-in music player offers storage for up to 4,000 tracks and supports a wide range of formats including MP3, WMA, AAC-LC and Linear PCM. Offered in a 4GB NWZ-WH303 version as well as a 16GB NWZ-WH505, Sony’s Walkman WH Series looks to be available in the near future although exact pricing and availability remain unknown.
