Pioneer Voice Monitoring Receiver VMR-M77, one-owner item. Found during my father's decluttering. It was used very little and stored for a long time, but I have confirmed it works with batteries. Both the operation and appearance are good. Accessories include: - femimi main unit (batteries not included) - Earphone microphone - Earphone tips, instruction manual, warranty card, etc. are not included. The earphones have been disinfected with alcohol, but they are still used items, so please consider this before purchasing.
