This Panasonic RQ-SX52 is one of the smallest Walkmans ever made. With a built-in rechargeable battery, it can play up to 70 hours of music. A smart additional penlight AA battery holder can easily be mounted on it so the player can play even longer. Very high quality: made of high-quality aluminium housing. This Walkman has probably never been used. All parts look as new! The rechargeable battery still recharges nicely! These batteries are still for sale. In original box with manuals, proof of warranty. The player functions as new; autoreverse and speed work perfectly. Sound with Dolby NR filter is individually switchable. The headphones are still in the original packaging. There is a remote control in the cord of the headphones and this gives access to all functions in addition to the volume of course. The charger has an English plug: an adapter is included! In short, a very special personal cassette player of an unparalleled quality!
