Ok, I rarely say that form Thanko’s product but this new Earphone with Built-tin alarm, the EARINALM, are just pure genius! Take you average earphones and add within its remote control a little alarm clock and voila! Just set the alarm whenever you want and if you fall asleep while listening to music in the train your little earphones with built-in alarm will wake you up immediately by replacing your tune with a good old annoying alarm sound.
Honestly this does not look much but this is may be a killer gadget to own if you often miss your Bus/Train/Metro stop.

Go and check Thanko’s store if you are interested, these new EARINALM are quite pretty cheap and already available for just 2980 Yen.
