I remember the old overhead Philips headphones from the 2022s and a Japanese battery-powered CD player. everything is very old primitive and the volume was not enough. Why am I saying all this .) At the moment, the respected Sony company slips us a frank g. consciously because they know everything about sound quality. If you want to experience the quality then (it will be difficult) find a CD player and headphones with a frequency range of at least that of the MDR 1R good luck! ps. 2 minuses at least 3 points for this. From the point of view of sound quality, this is the main thing, right?
