Shock resistant memory
For those of you intending to use your personal CD player while on the move, shock-resistant memory is a useful feature. Shock-resistant memory means that the player stores at least 10 seconds of the song in advance, so if a shock occurs and there is an interruption in the sound, you will not hear this thanks to the interruption free buffer. This is an essential feature for gym users and joggers who like to listen to their personal stereos while exercising.
