The words "Sony Walkman" will mean completely different things to each one of you depending on what generation you're from. To some, it'll be a chunky grey cassette player while to others, it's a funky looking little MP3 player. Though it may no longer be the household name it once was, it has just made its return in a pretty impressive way. The Sony Walkman ZX2, which debuted at CES 2015 this week, is only for the most committed of audiophiles. It comes with 128GB of built-in memory and was created specifically for ultra-high quality recordings, supporting digital music files up to 192 kHz/24 bit. The Sony Walkman ZX2 Hi-Res Digital Music Player is not available yet but when it is, it'll be priced at $1,200 (just a tad more than your old CD player).
