Remember the good ol’ Sony Walkman that introduced the concept of taking your music with you? It is probably a distant memory now. After phasing out the clunky Walkman in 2010, Sony is bringing it back in the form of a sleeker, more advanced Android-run Walkman ZX2 — without cassettes. This high-end player, at a stocky price of $1,200, is targeted at audiophiles, promising high-resolution playback and compatibility with all audio file formats. But given that none of Sony’s other players were as successful as the Walkman, it remains to be seen if the news of this expensive gadget will be music to the ears of the Millennials.
