MP3 music players have come a long way from the clunky, form-follows-function bricks that looked best when they were buried in your pocket. Times have changed and so have the players - this new series of ultra-thin "small wonders" from Tokyo's Strapya World are not only slim & trim, they don't look anything like MP3 players anymore.
This latter feature could possibly give rise to some difficult situations, as the following video illustrates:
Weighing just 20 grams (0.7 oz), the player is about the size of a credit card and almost as thin. One of the 6 available styles actually IS a gold credit card, with the others being a vintage camera, an old-style audio cassette tape, and three different chocolate bar flavors. The player's measurements are 5.4cm wide by 8.6cm long by 0.5cm thick (2.16" x 3.44" x 0.2").
The total price of 2,400 yen (around $26.70) plus shipping gets you a nicely filled out package that includes a USB Cable with a 2.5mm plug, an exchangeable adapter (2.5mm to 3.5mm), and stereo earphones with a 2.5mm plug that will NOT work with cell phones.
One notable feature of this MP3 player is that it can play music either through the included earphones or though a pair of speakers built into the player. How they squeezed a pair of speakers into a 1/5 of an inch thick device is beyond me. When fully charged (which takes 3 to 4 hours) the maximum playing time with earphones is up to 15 hours or, using only the speakers, about 4 to 5 hours.
Any other specs to note? Lessee... the file format is MP3WMA, stored memory capacity is 2GB, the USB format is USB2.0 and the file transfer speed is 8MB/s. Small wonders indeed!
