Powered performance
With its battery status display and improved power management R1 Mk4 works even better and longer with the our optional Backpack 3 and means you can enjoy R1’s rich mains powered performance where mains power is unavailable.

12 hours of mains-free listening
Backpack 3 attaches seamlessly to R1 and once fitted can be left permanently in place as it charges automatically whenever mains power is re-applied. A full charge will provide up to twelve hours of mains free listening depending on volume.

MR1 Bluetooth Speaker System
Backpack 3 is also compatible with our MR1 Bluetooth Speaker System.
