Hello Stefan! Thank you for the kind words and 5 star review! We’re thrilled to hear you're enjoying the CD player! As for your question: powering off the unit completely is generally the best option if you won’t be using it for a while, as it conserves energy and prolongs the life of the internal components. Standby mode is handy for quick access if you’re planning to use it again soon, it automatically turns on when connecting with Bluetooth device and provides a smoother experience between listening sessions. Hope that helps and thanks again for the fantastic feedback!
