Panasonic S-XBS RQ-S40V. Confirmed that AM radio can be heard with earphones. Cassette function not confirmed. Please purchase only if you understand the condition. Since the cassette function is unconfirmed, it is considered junk. This is a no-claims, no-returns item. Returns are not accepted. Thank you. The battery is a third-party SONY battery. I have also confirmed the volume control with earphones. The confirmation was done with AA batteries. If you want to buy it as a set with an MD Walkman, please comment for a discount.
